What is Familial Hypercholesterolemia (FH)
FH is an autosomal dominant disorder characterized by very high LDL cholesterol (serum LDL-C >190 mg/dl)
It is strongly associated with premature coronary artery disease
An individual with FH has a 50% chance of passing the genes on to their kids
FH has an estimated worldwide prevalence of 1 in 200 to 250 people1
Indian prevalence is 1 in 3502

How is FH diagnosed?

A precise diagnosis of FH is made by a genetic test conducted over a simple blood sample. An expert panel convened by the Familial Hypercholesterolemia Foundation recommends genetic testing as the standard of care for patients who have a definite or probable diagnosis for FH based on clinical factors and family history.

Summary of the Study
  • 100 unrelated patients of Indian origin examined
  • 38 mutations in 47 samples detected
  • 10 novel variants discovered
  • These mutations significantly increase incidence of FH in Indian patient population
  • Variations in APOB gene in Indian population different from Western population
  • NGS technology helped to identify new mutations in APOB gene, suggesting that in less studied populations it is better to sequence the whole gene rather than test for specific mutations.
Outcomes of the Study
  • Study demonstrates genetic heterogeneity of FH in India
  • The variants observed were different from those described in Western populations
  • NGS technology helped to identify new mutations in APOB gene
  • Research leads to formation of first ever database of genetic variations for Indian Population
