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]

PLA2G4E-AS1 (HGNC:51419): (PLA2G4E antisense RNA 1)

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.21929625).

The c.2164A>G (p.I722V) alteration is located in exon 18 (coding exon 18) of the PLA2G4E gene. This alteration results from a A to G substitution at nucleotide position 2164, causing the isoleucine (I) at amino acid position 722 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
