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]

The c.1091A>G (p.N364S) alteration is located in exon 9 (coding exon 9) of the PIK3R3 gene. This alteration results from a A to G substitution at nucleotide position 1091, causing the asparagine (N) at amino acid position 364 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
