Genes affected

PLA2G4F (HGNC:27396): (phospholipase A2 group IVF) Predicted to enable calcium ion binding activity; calcium-dependent phospholipase A2 activity; and calcium-dependent phospholipid binding activity. Predicted to be involved in glycerophospholipid catabolic process. Predicted to act upstream of or within several processes, including arachidonic acid secretion; cellular response to antibiotic; and prostaglandin biosynthetic process. Predicted to be located in cytoplasm. Predicted to be active in cytosol; ruffle membrane; and vesicle. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.39251888).
