Rare Heart Gene Mutations Found in India
5 Nov
Summary
- Two rare genetic mutations linked to HCM discovered.
- Mutations identified in 160 patients from Telangana, India.
- Findings may enable earlier diagnosis and targeted treatments.
Researchers in India have made a significant breakthrough in understanding Hypertrophic Cardio-Myopathy (HCM), a life-threatening inherited heart condition. Scientists from CSIR-CCMB, Osmania University, and AIG Hospitals identified two rare genetic mutations associated with the disease. These mutations were found within the MYH7 gene, which codes for a critical protein involved in heart muscle contraction.
The study analyzed 160 HCM patients and 178 healthy individuals from Telangana. Two specific, rare mutations were pinpointed in critical regions of the myosin protein, suggesting they disrupt normal heart function. These variants were observed in individuals with varying degrees of HCM severity and were absent in healthy populations and global databases, indicating their rarity and potential concentration within South Asian populations.
This groundbreaking research, published in the Journal of the American College of Cardiology: Asia, could lead to improved diagnostic tools and personalized treatment strategies for HCM. It underscores the importance of genetic research in uncovering the basis of cardiovascular diseases and paves the way for future precision diagnosis and population screening initiatives.
