For over 15 years, Dr Anthony Shum, a pulmonologist at the University of California, San Francisco has been studying a rare genetic disorder called the COPA Syndrome. It stands for coatomer subunit alpha and is a rare, inherited disorder that affects the lungs, joint, and kidney. The National Organization for Rare Disorder also notes that it is a genetic autoimmune disorder that is caused by mutations in the COPA gene. This disease affects families unpredictably—some individuals with the mutation develop severe lung damage early in life, while others remain completely healthy. Now, Shum’s team has discovered a protective genetic variant that may offer new hope for treatment.

A Breakthrough

Researchers found that some relatives of COPA Syndrome patients stayed healthy despite carrying the same COPA gene mutation that causes the disease. The key difference? These unaffected individuals had a protective version of another gene called HAQ-STING.

When scientists introduced HAQ-STING into diseased lung cells from COPA patients, the cells returned to a balanced state, suggesting that this gene could be used as a therapy.

“We really think HAQ-STING could be a gene therapy tool and a step toward a cure,” said Shum, whose findings were published in the Journal of Experimental Medicine.

Families Who Solved The Mystery

Shum’s journey into COPA Syndrome research began in 2011 when he treated a young woman, Letasha, who had severe lung bleeding. Her mother, Betty Towe, mentioned that Letasha’s sister, Kristina, had suffered from similar symptoms. Over the years, Betty had taken both daughters on a four-hour trip to UCSF for treatment. After tracing their family history, Shum discovered that their distant relatives in Texas and Oakland also had lung problems and arthritis. In 2015, Shum, along with scientists from Baylor College of Medicine and Texas Children’s Hospital identified the COPA gene mutation. They realized that it was the common factor behind the illness. However, only some of the 30 individuals with the mutation actually developed symptoms, leaving a major question unanswered.

The Domino Effect

It was established that it occurs when a mutated COPA gene causes another gene STING to go overdrive. The STING that helps fight infections in COPA patients, remain permanently active, which leads to chronic inflammation that damages the lungs, kidneys, and joints. In 2020, while studying STING’s role in the disease, researchers discovered a key variation: HAQ-STING. This version of STING, present in about one-third of the population, appeared to neutralize the harmful effects of the COPA mutation.

To confirm their theory, the scientists needed both affected and unaffected family members to participate in the testing. Letasha, Kristina and Betty immediately volunteered. The researchers then analyzed DNA samples from 26 COPA patients and their healthy relatives. They also conducted CT scans and blood tests to ensure that unaffected members did not have any hidden symptoms. When the findings were all clear, it was revealed that all the healthy individuals had HAQ-STING, while none of the COPA patients did. This was the first known case of a common gene variant completely protecting against a severe genetic disease.

Encouraged by this discovery, researchers tested HAQ-STING’s effects in a lab setting. They introduced it into diseased lung cells from COPA patients, and the cells returned to normal function.

Way Ahead

Shum believes HAQ-STING could lead to game-changing treatments, including:

  • Prenatal gene therapy for babies diagnosed with COPA Syndrome before birth
  • Aerosol delivery of HAQ-STING for adults, directly targeting the lungs

Before publishing their findings, Shum called Betty with the news—her own HAQ-STING gene had protected her from the disease. He also informed Letasha and Kristina, who were overwhelmed with relief and joy.

“We always believed Dr. Shum would get to the bottom of it,” said Letasha. “This discovery is going to change lives.”

‘Work Stress Makes You Gay’: Why Malaysian Minister's Remark Proves The Need To Understand Sex, Gender And Sexuality

Updated Jan 30, 2026 | 12:10 PM IST

SummaryMalaysian minister Zulkifli Hasan’s claim that work stress can make people gay sparked backlash and misinformation. Experts stress there is no scientific evidence linking stress to sexual orientation, highlighting the need to understand the clear differences between sex, gender and sexuality, which are distinct biological, social and psychological concepts.

Work stress could make you gay, said a Malaysian minister Zulkifli Hasan, as continued government intervention of what is described as 'sexually deviant behavior' has pressured the country's LGBTQ community. This happened two weeks after religious authorities and police acted on complaints from a sultan and Islamist politicians that a camping retreat was promoting the LGBTQ lifestyle, reported South China Morning Post.

Religious Affairs Minister Hasan on Tuesday said that work stress could be among many other factors that is pushing people into sexual orientations other than heterosexuality. “Societal influence, sexual experiences, work stress and other personal factors come under this category [of possible causes],” Zulkifli said in a written parliamentary reply to a question by Siti Zailah Mohd Yusoff, a lawmaker with the opposition Islamist party PAS.

He cited a 2017 study by Sulaiman et.al., that said such elements "can contribute to the increase in LGBT acts".

His comments have attracted a lot of backlash, with many people on social media mocking him. A social media user Muaz Zam said, "By this logic, I am genuinely shocked my entire office isn't gay by now". Another one read: "In other words: they never work hard in the parliament."

However, these claims are not scientifically back. Work related stress can impact a person, but cannot change their sexuality. It can, however, cause health effects. What it does not do is change one's sexuality and this is why one should know the difference about gender, sex and sexual orientation or sexuality.

'Work Stress Makes You Gay': The Difference Between Gender vs Sex

Work Stress makes you gay (Canva)

While these both terms are often used interchangeably in official forms, there is a difference between the two.

As per the Council of Europe, gender is an area that cuts across thinking about society, law, politics, and culture.

Definition Of Gender vs Sex by WHO

The World Health Organization notes that sex refers to: "the different biological and physiological characteristics of males and females, such as reproductive organs, chromosomes, hormones, etc.”

Whereas, gender refers to: "the socially constructed characteristics of women and men – such as norms, roles and relationships of and between groups of women and men. It varies from society to society and can be changed. The concept of gender includes five important elements: relational, hierarchical, historical, contextual and institutional. While most people are born either male or female, they are taught appropriate norms and behaviours – including how they should interact with others of the same or opposite sex within households, communities and work places. When individuals or groups do not “fit” established gender norms they often face stigma, discriminatory practices or social exclusion – all of which adversely affect health."

Definition Of Gender vs Sex by The European Institute For Gender Equality

Sex refers to the biological and physiological characteristics that define humans as female or male. These sets of biological characteristics are not mutually exclusive, as there are individuals who possess both, but these characteristics tend to differentiate humans as females or males.”

Gender refers to the social attributes and opportunities associated with being female and male and to the relationships between women and men and girls and boys, as well as to the relations between women and those between men. These attributes, opportunities and relationships are socially constructed and are learned through socialisation processes. They are context- and time-specific, and changeable. Gender determines what is expected, allowed and valued in a woman or a man in a given context. In most societies, there are differences and inequalities between women and men in responsibilities assigned, activities undertaken, access to and control over resources, as well as decision-making opportunities. Gender is part of the broader sociocultural context. Other important criteria for sociocultural analysis include class, race, poverty level, ethnic group and age.”

The main difference is that gender is a social construct, whereas sex is the biologically labelled term based on organs and hormones.

What Is Sexuality?

LGBTQ community (Canva)

As per the American Psychological Association (APA), sexuality is the capacity to derive pleasure from various forms of sexual activity and behavior. The Lanarkshire Sexual Health describes sexual orientation as a way to describe the feelings you have for someone you fancy or are attached to.

While sexuality can change overtime, it is not a choice. There is no evidence that sexual orientation can be forced to change through therapy.

Can Stress Impact Sexuality?

While stress can impact sexual function by reducing libido, causing fatigue, and triggering hormonal changes, it does not change one's sexual orientation. Jason Teoh, who writes on LGBTQ issues, project partner at NSW Department of Planning, Housing and Infrastructure, notes: "Sexual orientation is not caused by stress. It is not caused by trauma, influence or difficult life circumstances."

The WHO notes: sexual orientation is a natural, stable part of human identity shaped by biology, genetics, and early development. The WHO removed homosexuality from its disease classification in 1990. The American Psychiatric Association did the same in 1973.

Parkinson's disease is a progressive, neurodegenerative movement disorder caused by the loss of dopamine-producing brain cells, primarily affecting people over 60. Apart from motor loss, the disease also causes cognitive decline, depression, anxiety and swallowing problems.

The first symptom may be a barely noticeable tremor in just one hand or sometimes a foot or the jaw. Over time, swinging your arms may become difficult and your speech may become soft or slurred. The disorder also causes stiffness, slowing of movement and trouble with balance that raises the risk of falls.

However, before clear symptoms begin to appear, Neurologist Rachel Dolhun says certain signs may help identify the onset of the disease decades before it is diagnosed.

“It’s important to stress that not everyone who has these symptoms goes on to develop Parkinson’s,” said neurologist Rachel Dolhun. “But we know that in some people, these can be some of the earliest signs," she told The Washington Post.

Here is what you should look out for:

1. Loss Of Smell

Loss of smell, or hyposmia, is a common and early non-motor symptom of Parkinson's disease, affecting up to 90 percent of patients. This symptom can significantly impact quality of life by reducing the enjoyment of food and diminishing appetite.

While strongly linked to Parkinson's, smell loss can also stem from other causes, including sinus problems, COVID-19, or aging.

2. Acting Out Dreams

Acting out dreams, known as REM Sleep Behavior Disorder (RBD), involves physically enacting vivid, often unpleasant dreams through shouting, punching, or kicking during sleep.

This typically happens because the brainstem fails to temporarily paralyze muscles during REM sleep. It is a strong early warning sign of Parkinson's disease, often appearing years or decades before motor symptoms. About 50 percent of people with Parkinson's experience RBD.

3. Constipation

Constipation is a very common and significant non-motor symptom of Parkinson's disease that is caused by nerve changes slowing gut muscles and potentially exacerbated by low activity and dehydration.

Constipation can also be caused by Parkinson's medications such as anticholinergics, amantadine and other common drugs such as opioids, iron/calcium antacids.

4. Dizziness As You Stand

The autonomic nervous system fails to properly constrict blood vessels or increase heart rate upon standing, often due to a lack of norepinephrine. This causes the autonomic nervous system to fail in regulating blood pressure. Over time, this leads to Neurogenic Orthostatic Hypotension.

Beyond dizziness, symptoms include blurred vision, weakness, fatigue, cognitive "fog," and "coat hanger pain" (pain in the neck/shoulders). Often times, patients experience dizziness in the morning or immediately after meals.

Diagnosing Parkinson’s disease is mostly a clinical process, meaning it relies heavily on a healthcare provider examining your symptoms, asking questions and reviewing your medical history. Various imaging and diagnostic tests used to detect disease includes CT scan, PET scan, MRI scan and genetic testing.

What Is Cold Urticaria? Doctors Warn Of Painful Allergy Caused By Cold Exposure

Updated Jan 29, 2026 | 11:00 PM IST

SummaryDoctors are warning about cold urticaria, a painful cold allergy that causes itchy red rashes, swelling, and hives when skin is exposed to cold air, water, or sudden temperature changes.

Beyond icy roads and fogged-up car windscreens, the coldest season can also bring on a painful condition that leaves the skin covered in red, itchy patches. Doctors have issued a warning about this lesser-known illness, which tends to worsen in low temperatures.

The condition, known as cold urticaria, affects around one in 2,000 people. It causes swelling and itching of the skin when it comes into contact with cold air, cold water, or even air conditioning. Red welts or hives can appear within minutes, and the discomfort may last for as long as two hours.

What Is Cold Urticaria?

Cold urticaria is an uncommon condition in which the body reacts abnormally to cold temperatures. It typically causes rashes or hives after exposure to cold air, water, food, or drinks. In some cases, symptoms can be more serious. According to the Cleveland Clinic, the condition may sometimes be linked to an underlying blood cancer or an infectious illness.

Griet Voet, head of a dermatology clinic in Ghent, Belgium, as per Express UK, said the condition is often confused with common winter skin problems such as eczema. “This is not just dry skin caused by cold weather, it is a genuine allergic reaction to cold,” she explained. In more severe cases, large areas of the body may be affected, particularly after swimming in cold water or spending extended periods outdoors. This can lead to intense itching, facial flushing, and even headaches, stomach pain, or fainting. Sudden temperature shifts, such as moving from a warm indoor space into cold outdoor air, can also trigger symptoms. Drinking ice-cold beverages may cause swelling of the lips, mouth, or throat.

Cold Urticaria: What Are The Symptoms Of This Disease?

Symptoms of cold urticaria differ from person to person and can range from mild to severe. They may be limited to a small patch of skin or spread across the entire body.

The most common sign is a skin rash that appears after contact with something cold. The rash usually develops once the exposure ends, as the skin begins to warm up.

The rash may include:

  • Hives, bumps, or raised welts
  • Itching
  • Redness
  • Swelling
Other possible symptoms include:

  • Fatigue
  • Fever
  • Headache
  • Joint pain
In very rare and severe cases, a person may develop a reaction that affects the whole body, such as:

  • Fainting
  • Heart palpitations
  • A severe allergic reaction known as anaphylaxis
  • Shortness of breath or wheezing

How Is Cold Urticaria Diagnosed?

A medical professional can often diagnose cold urticaria using a simple test. An ice cube is placed on the skin, usually on the arm, for a few minutes and then removed. If a hive or rash appears several minutes later, the result is considered positive.

In cases of familial cold urticaria, diagnosis may involve exposure to cold air for a longer duration.

Doctors may also suggest blood tests to check for any underlying illness or infection that could be contributing to the condition.
