Genes affected
GNA12 (HGNC:4380): (G protein subunit alpha 12) Predicted to enable D5 dopamine receptor binding activity; G-protein beta/gamma-subunit complex binding activity; and GTPase activity. Involved in regulation of TOR signaling and regulation of proteasomal ubiquitin-dependent protein catabolic process. Located in focal adhesion. [provided by Alliance of Genome Resources, Apr 2022]
AMZ1 (HGNC:22231): (archaelysin family metallopeptidase 1) Predicted to enable metal ion binding activity and metallopeptidase activity. Predicted to be involved in proteolysis. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2024The c.772G>A (p.D258N) alteration is located in exon 4 (coding exon 4) of the GNA12 gene. This alteration results from a G to A substitution at nucleotide position 772, causing the aspartic acid (D) at amino acid position 258 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
