Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_003629.4(PIK3R3):​c.1192G>T​(p.Asp398Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.00000124 in 1,612,516 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. D398H) 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]
