Notes
aka c.551G>A, p.Cys184Tyr or C184Y; also known as FH Glasco and FH Rome-2; note also presence of c.551G>C (p.Cys184Ser or C184S), which is also likely to be pathogenic according to ClinVar FH Glasco is one of the most common South Asian and non-Finnish European FH mutations in ExAC/Broad data. Reported in ClinVar as pathogenic for familial hypercholesterolemia and therefore increased risk for coronary artery disease
