Genes affected

ARHGAP27 (HGNC:31813): (Rho GTPase activating protein 27) This gene encodes a member of a large family of proteins that activate Rho-type guanosine triphosphate (GTP) metabolizing enzymes. The encoded protein may pay a role in clathrin-mediated endocytosis. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

Feb 02, 2022

The c.1625C>T (p.A542V) alteration is located in exon 17 (coding exon 16) of the ARHGAP27 gene. This alteration results from a C to T substitution at nucleotide position 1625, causing the alanine (A) at amino acid position 542 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
