Genes affected
ARHGAP17 (HGNC:18239): (Rho GTPase activating protein 17) RICH1 is a GTPase-activating protein (GAP). GAPs stimulate the intrinsic GTP hydrolysis of small G proteins, such as RHOA (MIM 165390), RAC1 (MIM 602048), and CDC42 (MIM 116952).[supplied by OMIM, Apr 2004]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 17, 2023The c.1897G>A (p.V633I) alteration is located in exon 19 (coding exon 19) of the ARHGAP17 gene. This alteration results from a G to A substitution at nucleotide position 1897, causing the valine (V) at amino acid position 633 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
