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 GeneticsJan 04, 2024The c.258G>A (p.M86I) alteration is located in exon 2 (coding exon 2) of the GNA14 gene. This alteration results from a G to A substitution at nucleotide position 258, causing the methionine (M) at amino acid position 86 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
