Genes affected
ARHGAP22 (HGNC:30320): (Rho GTPase activating protein 22) This gene encodes a member of the GTPase activating protein family which activates a GTPase belonging to the RAS superfamily of small GTP-binding proteins. The encoded protein is insulin-responsive, is dependent on the kinase Akt and requires the Akt-dependent 14-3-3 binding protein which binds sequentially to two serine residues. The result of these interactions is regulation of cell motility. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 28, 2022The c.1334G>A (p.G445D) alteration is located in exon 9 (coding exon 9) of the ARHGAP22 gene. This alteration results from a G to A substitution at nucleotide position 1334, causing the glycine (G) at amino acid position 445 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
