Genes affected
ARHGAP42 (HGNC:26545): (Rho GTPase activating protein 42) This gene encodes a Rho GTPase-activating protein (RhoGAP), and member of the GRAF or BAR-PH family of proteins. Expression of this gene is enriched in vascular smooth muscle cells and the encoded protein inhibits RhoA activity to regulate vascular tone and control blood pressure. A mutation in the first intron of this gene modulates its expression and is associated with reduced blood pressure in human patients with borderline hypertension. [provided by RefSeq, Jul 2017]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 12, 2023The c.956C>T (p.P319L) alteration is located in exon 10 (coding exon 10) of the ARHGAP42 gene. This alteration results from a C to T substitution at nucleotide position 956, causing the proline (P) at amino acid position 319 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
