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]

GNA12 links:

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]

Jun 09, 2022

The c.1025G>T (p.R342L) alteration is located in exon 4 (coding exon 4) of the GNA12 gene. This alteration results from a G to T substitution at nucleotide position 1025, causing the arginine (R) at amino acid position 342 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
