Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PP3_ModerateBS2

The NM_003629.4(PIK3R3):​c.797G>A​(p.Arg266His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000375 in 1,597,940 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R266C) has been classified as Uncertain significance.

Genes affected
PIK3R3 (HGNC:8981): (phosphoinositide-3-kinase regulatory subunit 3) Phosphatidylinositol 3-kinase (PI3K) phosphorylates phosphatidylinositol and similar compounds, which then serve as second messengers in growth signaling pathways. PI3K is composed of a catalytic and a regulatory subunit. The protein encoded by this gene represents a regulatory subunit of PI3K. The encoded protein contains two SH2 domains through which it binds activated protein tyrosine kinases to regulate their activity. [provided by RefSeq, Jun 2016]
P3R3URF-PIK3R3 (HGNC:54999): (P3R3URF-PIK3R3 readthrough) This locus represents naturally occurring readthrough transcription between the neighboring genes LOC110117498 and PIK3R3. The readthrough transcript encodes a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Apr 2017]
