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]

Neutral lipid storage myopathy Pathogenic:1
Likely pathogenic, no assertion criteria providedclinical testingNeuromuscular Department, Shariati Hospital, Tehran University of Medical SciencesApr 03, 2020A 39-year-old woman, with proximal weakness of left upper limb since 9 years ago. She had five healthy siblings and the parents were second cousins. The electromyography was myopathic. The CK was 2110 IU/L and the muscle biopsy revealed lipid droplets in Oil Red Oil staining and few rimmed vacuoles. Peripheral blood smear indicated a Jordan anomaly. -
