Genes affected
GNA14 (HGNC:4382): (G protein subunit alpha 14) This gene encodes a member of the guanine nucleotide-binding, or G protein family. G proteins are heterotrimers consisting of alpha, beta and gamma subunits. The encoded protein is a member of the alpha family of G proteins, more specifically the alpha q subfamily of G proteins. The encoded protein may play a role in pertussis-toxin resistant activation of phospholipase C-beta and its downstream effectors.[provided by RefSeq, Feb 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2024The c.505G>A (p.V169M) alteration is located in exon 4 (coding exon 4) of the GNA14 gene. This alteration results from a G to A substitution at nucleotide position 505, causing the valine (V) at amino acid position 169 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
