We report CGL1 in two Saudi female siblings with lipoatrophy, diabetes mellitus, hypertriglyceridemia, steatohepatitis, and acanthosis due to very rare homozygous 1-acylglycerol-3-phosphate O-acyltransferase β (AGPAT2) genetic variant. This evidence concerns the gene AGPAT2 and hypertriglyceridemia.
