1-acylglycerol-3-phosphate O-acyltransferase 2

The AGPAT2 gene encodes an enzyme that is located within the endoplasmic reticulum membrane. It plays a role in phospholipid biosynthesis. Mutations cause autosomal recessive generalized lipodystrophy characterized by absence of adipose tissue and severe insulin resistance. The disorder is apparent from birth or early infancy. Other clinical features include acanthosis nigricans, muscular hypertrophy, hepatomegaly, altered glucose tolerance or diabetes mellitus, and hypertriglyceridemia.
