Genes affected

PLA2G4E (HGNC:24791): (phospholipase A2 group IVE) This gene encodes a member of the cytosolic phospholipase A2 group IV family. Members of this family are involved in regulation of membrane tubule-mediated transport. The enzyme encoded by this member of the family plays a role in trafficking through the clathrin-independent endocytic pathway. The enzyme regulates the recycling process via formation of tubules that transport internalized clathrin-independent cargo proteins back to the cell surface. [provided by RefSeq, Jan 2017]

Collection Method: clinical testing

The c.1945C>T (p.R649W) alteration is located in exon 17 (coding exon 17) of the PLA2G4E gene. This alteration results from a C to T substitution at nucleotide position 1945, causing the arginine (R) at amino acid position 649 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
