Genes affected
ARHGAP32 (HGNC:17399): (Rho GTPase activating protein 32) RICS is a neuron-associated GTPase-activating protein that may regulate dendritic spine morphology and strength by modulating Rho GTPase (see RHOA; MIM 165390) activity (Okabe et al., 2003 [PubMed 12531901]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.5726A>G (p.K1909R) alteration is located in exon 22 (coding exon 22) of the ARHGAP32 gene. This alteration results from a A to G substitution at nucleotide position 5726, causing the lysine (K) at amino acid position 1909 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
