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 GeneticsApr 08, 2024The c.5866C>T (p.P1956S) alteration is located in exon 22 (coding exon 22) of the ARHGAP32 gene. This alteration results from a C to T substitution at nucleotide position 5866, causing the proline (P) at amino acid position 1956 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
