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

August 18 marks World Breast Cancer Research Day, a day that reminds us that every major breakthrough in cancer care has its roots in research. The medicines that are prescribed, the diagnostic technologies that we use, the targeted therapies that we offer and our growing understanding of why cancers develop and spread, are all outcomes of regular scientific research.
India carries one of the world's largest cancer burdens. According to IARC's GLOBOCAN 2022 estimates, India recorded approximately 1.41 million new cancer cases and more than 916,000 cancer deaths in 2022. Breast cancer alone was the leading cancer among Indian women and also the leading cancer overall.
India as a country, has a large and diverse patient population, significant clinical expertise, strong medical institutions and a pharmaceutical industry with enormous manufacturing capabilities. But there is a crucial gap between manufacturing what the world has already discovered and researching newer medical opportunities.
A significant proportion of cutting-edge cancer research continues to emerge from countries with substantially larger and more established research ecosystems. When scientific discoveries, new molecules, diagnostic technologies or treatment approaches are developed elsewhere, Indian patients benefit from them at a later stage.
We have limited institutes that have made important contributions to cancer care and research. But considering India's population and cancer burden, the scale of research infrastructure needs to expand substantially. We need more dedicated cancer-research institutes, stronger university hospital industry collaborations, modern laboratories, biobanks, genomic databases, data-science capabilities and trained physician-scientists.
Cancer is not just one disease. It comprises of multiple biological subtypes, and the way a tumour behaves can vary significantly between individuals and populations. Therefore, India needs research that focusses specifically towards Indian patients.

India has a formal Clinical Trials Registry, and the registry currently records more than 100,000 trials across areas of medicine.
For eligible patients, participation in an appropriate clinical trial may provide access to an investigational therapy or treatment strategy that is not yet routinely available. Clinical trials generate evidence that can improve future treatment for thousands or millions of patients.

We need to create an ecosystem that moves from discovery to translation to patient care. That means incentivizing research institutions and researchers, supporting young physician-scientists, strengthening public-private partnerships and making it easier for promising discoveries to move from laboratories into clinical development.
We need to have an ecosystem, where healthcare research, particularly research addressing diseases with an enormous Indian burden should receive a much greater and more targeted share of national research investment. A large, diverse population can generate valuable real-world evidence. Large patient cohorts can help researchers understand disease patterns. Indian genetic and molecular data can help answer questions that may not be adequately addressed through studies conducted in other countries.
India has already demonstrated that it can serve the world as a pharmaceutical manufacturing powerhouse. We should look at also becoming the research hub for the world by combining our pharmaceutical manufacturing strength, clinical expertise, technology capabilities and patient population.
The opportunity is already in front of us.
What we need now is the policy ambition to implement it.

If you believe having a healthy body mass index (BMI) means you have a low risk of heart disease, you may be wrong. A new study suggests that abdominal fat may predict cardiovascular disease risk better than BMI alone.
The study, published in the Journal of the American College of Cardiology (JACC), found that failing to account for waist circumference (WC) or waist-to-hip ratio (WHR) may lead to misclassification of cardiovascular disease risk.
“Indeed, it appears that WC and WHR reclassify risk defined by traditional BMI thresholds,” said Michael J. Blaha, director of clinical research at the Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease.
“We saw individuals with clinically determined normal weight who had elevated central adiposity and high WHR, associating them with higher risk across most outcomes,” Blaha added.
BMI is calculated by dividing weight in kilograms by height in meters squared and is commonly used to diagnose overweight and obesity. However, BMI does not show where body fat is distributed.
The study examined whether adding WC and WHR to BMI could better predict future cardiovascular risk. Researchers looked at more than 260,000 people over an average of 20 years. They found that central adiposity could identify cardiovascular risk that BMI alone may miss.
Among people classified as having normal weight by BMI:
People with normal weight or overweight who had clinically defined high WC or WHR had a 15%–50% greater risk for most heart problems.
People with obesity and low WC did not have a significantly different risk of outcomes compared with those who had normal weight and low WC, except for all-cause mortality, for which their risk was significantly lower.
“Our findings emphasize the critical role of identifying elevated central adiposity, even in individuals with a normal BMI or with a BMI in the overweight range. Relying solely on BMI may result in misclassification of cardiovascular risk across a wide range of cardiovascular outcomes,” said Zeina A. Dardari, lead author of the study.
“We encourage clinicians to consider central adiposity distribution across the entire BMI spectrum when evaluating cardiovascular risk in primary prevention settings,” she added.
The researchers did not have information on several factors that can influence cardiovascular disease risk, including:
The study also included only one assessment of waist circumference and waist-to-hip ratio. This limited the researchers' ability to understand how changes in abdominal fat accumulation over time may influence cardiovascular disease risk.

Organ donation is one of the most profound ways in which we can give the gift of life to another person. World Organ Donation Day, observed every year on August 13, is an opportunity to raise awareness about organ donation, address common myths and encourage more people to consider pledging their organs. India has a large number of patients waiting for organ transplants, including transplants of the liver, kidney, heart, pancreas, intestine and other organs and tissues.
Despite the significant need, organ donation rates remain low, with lack of awareness and several misconceptions continuing to be major barriers. One organ donor can potentially save multiple lives. However, for this to happen, it is important that people understand the process and make an informed decision about organ donation during their lifetime.
For most organs, donation after brain death is possible when the brain has permanently stopped functioning, but the heart is still beating, which generally occurs in an intensive care setting. Corneas can also be donated after death within a limited time period. This is why pledging your organs during your lifetime and discussing your decision with your family is important.
Organ retrieval is performed by trained medical specialists in an operating theatre. The surgical incision is carefully closed after the procedure, and the body is not mutilated.

A healthy person who is found suitable for living kidney donation through the required medical evaluation can generally continue their normal life after donation. The remaining kidney is capable of maintaining normal kidney function.
Kidney donation does not mean that a healthy donor has to take lifelong medication simply because they have donated a kidney. Some pain medication may be required during the initial recovery period, while the remaining healthy kidney continues to perform its function.
According to the source material, kidney donors do not generally need specific dietary restrictions solely because they have donated a kidney, as the remaining kidney continues to maintain normal kidney function.
Both men and women who donate a kidney can have children. For women, the source recommends waiting one year after donation before becoming pregnant to allow the body to recover completely.
Age alone does not determine whether someone can donate. The health of the donor and the condition of the organs are important considerations, and suitability is determined through medical evaluation.

• Consider pledging your organs during your lifetime and communicate your decision clearly to your family.
• Talk to your family, friends and colleagues about organ donation and help dispel common myths.
• Encourage community organisations to participate in creating awareness around organ donation.
• Do not assume that you are medically unfit to donate. A team of medical experts evaluates the donor and determines suitability.
• Organ donation is a completely voluntary decision. No individual should be pressured into donating an organ.
• Patients waiting for an organ transplant should approach a licensed transplant hospital and complete the necessary registration formalities, including through the NOTTO system.
Organ donation is ultimately about giving someone another chance at life. We should not take our organs with us; they can be used to save lives and give hope to those waiting for a transplant.
