Genes affected
GNA15 (HGNC:4383): (G protein subunit alpha 15) Enables G protein-coupled receptor binding activity. Involved in positive regulation of cytosolic calcium ion concentration involved in phospholipase C-activating G protein-coupled signaling pathway. Predicted to be located in plasma membrane. Predicted to be part of heterotrimeric G-protein complex. [provided by Alliance of Genome Resources, Apr 2022]
GNA15-DT (HGNC:55293): (GNA15 divergent transcript)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 21, 2023The c.550C>T (p.R184C) alteration is located in exon 4 (coding exon 4) of the GNA15 gene. This alteration results from a C to T substitution at nucleotide position 550, causing the arginine (R) at amino acid position 184 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
