Genes affected
ARHGAP15 (HGNC:21030): (Rho GTPase activating protein 15) RHO GTPases (see ARHA; MIM 165390) regulate diverse biologic processes, and their activity is regulated by RHO GTPase-activating proteins (GAPs), such as ARHGAP15 (Seoh et al., 2003 [PubMed 12650940]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 03, 2023The c.749G>A (p.R250Q) alteration is located in exon 9 (coding exon 8) of the ARHGAP15 gene. This alteration results from a G to A substitution at nucleotide position 749, causing the arginine (R) at amino acid position 250 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
