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.

The c.1078G>A (p.A360T) alteration is located in exon 13 (coding exon 12) of the ARHGAP27 gene. This alteration results from a G to A substitution at nucleotide position 1078, causing the alanine (A) at amino acid position 360 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
