She was a compound heterozygote for a p.G236Gfs*15 deletion and a p.G215E missense mutation at LPL, as was one sister with hypertriglyceridemia and pancreatitis during pregnancy.
In Eastern Québec, two major lipoprotein lipase (LPL) gene mutations, P207L and G188E, lead to complete LPL deficiency in homozygote subjects and contribute to elevated predisposition to hypertriglyceridemia in heterozygotes.
The two CAD patients heterozygous for the LPL(Gly188-->Glu) mutation, however, had hypertriglyceridemia and low plasma high density lipoprotein levels.
