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]

The c.140T>C (p.I47T) alteration is located in exon 1 (coding exon 1) of the ARHGAP42 gene. This alteration results from a T to C substitution at nucleotide position 140, causing the isoleucine (I) at amino acid position 47 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
