Genes affected
PNPLA2 (HGNC:30802): (patatin like phospholipase domain containing 2) This gene encodes an enzyme which catalyzes the first step in the hydrolysis of triglycerides in adipose tissue. Mutations in this gene are associated with neutral lipid storage disease with myopathy. [provided by RefSeq, Jul 2010]
PNPLA2 Gene-Disease associations (from GenCC):
  • neutral lipid storage myopathy
