Genes affected
ARHGAP21 (HGNC:23725): (Rho GTPase activating protein 21) ARHGAP21 functions preferentially as a GTPase-activating protein (GAP) for CDC42 (MIM 116952) and regulates the ARP2/3 complex (MIM 604221) and F-actin dynamics at the Golgi through control of CDC42 activity (Dubois et al., 2005 [PubMed 15793564]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2021The c.5198T>C (p.V1733A) alteration is located in exon 26 (coding exon 25) of the ARHGAP21 gene. This alteration results from a T to C substitution at nucleotide position 5198, causing the valine (V) at amino acid position 1733 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
