Familial hypercholesterolemia (FH) is a disease implicated with defects in either, Low density lipoprotein receptor gene (LDLR), Apolipoprotein B-100 gene (APOB), the Proprotein convertase subtilisin/kexin type 9 gene (PCSK9) or other related genes of the lipid metabolism pathway. The general characterization of heterozygous FH is by elevated low-density lipoprotein (LDL) cholesterol and early-onset cardiovascular diseases, while the more severe type, the homozygous FH results in extreme elevated levels of LDL cholesterol and usually death of an affected individual by early twenties. We present here a novel non-synonymous, missense mutation in exon 14 of the LDLR gene in two siblings of the Malay ethnicity discovered during an in-house genetic test. We postulate that their elevated cholesterol is due to this novel mutation and they are positive for homozygous FH. This is the first report of a C711Y mutation in patients with elevated cholesterol in Asia.
