Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The ENST00000397272.7(PLA2G4F):c.2219T>A(p.Met740Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000217 in 1,613,920 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M740V) has been classified as Likely benign.

Ambry Genetics

Jun 27, 2022

The c.2219T>A (p.M740K) alteration is located in exon 19 (coding exon 19) of the PLA2G4F gene. This alteration results from a T to A substitution at nucleotide position 2219, causing the methionine (M) at amino acid position 740 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
