Story summary

Researchers from West China Hospital and the University of Birmingham analyzed hypertrophic cardiomyopathy in Chinese patients, comparing 593 Chinese and 1,232 UK participants.
They found Chinese patients carried 52.8% rare genetic variants versus 13.6% in UK patients, with similar pathogenic variant rates.
Two mutations, MYBPC3 c.3624del and TNNT2 c.300C>G, were unique to the Chinese group.
The study advocates ethnicity-specific genetic databases to improve hypertrophic cardiomyopathy diagnosis and management.
