Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The ENST00000397272.7(PLA2G4F):c.2267G>A(p.Arg756His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000347 in 1,613,956 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/19 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. R756C) has been classified as Uncertain significance.

Ambry Genetics

Apr 22, 2024

The c.2267G>A (p.R756H) alteration is located in exon 19 (coding exon 19) of the PLA2G4F gene. This alteration results from a G to A substitution at nucleotide position 2267, causing the arginine (R) at amino acid position 756 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
