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 GeneticsMay 31, 2023The c.2546G>A (p.R849H) alteration is located in exon 20 (coding exon 20) of the ARHGAP17 gene. This alteration results from a G to A substitution at nucleotide position 2546, causing the arginine (R) at amino acid position 849 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
