Function
Regulatory subunit of phosphoinositide-3-kinase (PI3K), a kinase that phosphorylates PtdIns(4,5)P2 (Phosphatidylinositol 4,5- bisphosphate) to generate phosphatidylinositol 3,4,5-trisphosphate (PIP3). PIP3 plays a key role by recruiting PH domain-containing proteins to the membrane, including AKT1 and PDPK1, activating signaling cascades involved in cell growth, survival, proliferation, motility and morphology. Binds to activated (phosphorylated) protein- tyrosine kinases, through its SH2 domain... (Source: Uniprot)

Haploinsufficiency (HI) Score Details

HI Score:
0
HI Evidence Strength:
No Evidence for Haploinsufficiency (Disclaimer)
HI Evidence Comments:
Variants in PIK3R2 have been reported in individuals with megalencephaly-polymicrogyria-polydactyly-hydrocephalus syndrome. To date, all reported variants have been missense variants; the variants are believed to cause disease by a gain-of-function mechanism. See PMIDs 22729224, 23592320, and 23745724 for additional information.
