Genes affected
GNAI3 (HGNC:4387): (G protein subunit alpha i3) Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling pathways. G proteins are composed of 3 units: alpha, beta and gamma. This gene encodes an alpha subunit and belongs to the G-alpha family. Mutation in this gene, resulting in a gly40-to-arg substitution, is associated with auriculocondylar syndrome, and shown to affect downstream targets in the G protein-coupled endothelin receptor pathway.

Submissions by phenotype
Auriculocondylar syndrome 1 Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | 3billion | Jan 03, 2022 | The variant not observed in the gnomAD v2.1.1 dataset (PM2_M). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.881, 3CNET: 0.828, PP3_P). A missense variant is a common mechanism associated with Auriculocondylar syndrome 1 (PP2_P). Therefore, this variant is classified as uncertain significance according to the recommendation of ACMG/AMP guideline. - |
