Function
Heterotrimeric guanine nucleotide-binding proteins (G proteins) function as transducers downstream of G protein-coupled receptors (GPCRs) in numerous signaling cascades. The alpha chain contains the guanine nucleotide binding site and alternates between an active, GTP-bound state and an inactive, GDP-bound state. Signaling by an activated GPCR promotes GDP release and GTP binding. The alpha subunit has a low GTPase activity that converts bound GTP to GDP, thereby terminating the signal. Both GDP...

Haploinsufficiency (HI) Score Details

HI Score:
0
HI Evidence Strength:
No Evidence for Haploinsufficiency (Disclaimer)
HI Evidence Comments:
Heterozygous missense mutations of GNAI3 are associated with autosomal dominant auriculocondylar syndrome 1 (Rieder MJ et al. 2012, PMID: 22560091). At the time of this review, there is no evidence that haploinsufficiency of this gene is associated with an abnormal phenotype. Evidence suggests that gain of function mutations in GNAI3 may be responsible for the phenotype (PMID: 22560091).

Triplosensitivity (TS) Score Details

TS Score:
0
TS Evidence Strength:
No Evidence for Triplosensitivity (Disclaimer)
TS Evidence Comments:
No evidence of triplosensitivity found at the time of this review.
