Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP4

The NM_213600.4(PLA2G4F):​c.2312G>T​(p.Arg771Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000868 in 1,613,638 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/20 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R771C) has been classified as Uncertain significance.

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]
