Genes affected

GMIP (HGNC:24852): (GEM interacting protein) This gene encodes a member of the ARHGAP family of Rho/Rac/Cdc42-like GTPase activating proteins. The encoded protein interacts with the Ras-related protein Gem through its N-terminal domain. Separately, it interacts with RhoA through a RhoGAP domain, and stimulates RhoA-dependent GTPase activity. Alternative splicing results in multiple transcript variants.

The c.2620C>T (p.R874W) alteration is located in exon 21 (coding exon 21) of the GMIP gene. This alteration results from a C to T substitution at nucleotide position 2620, causing the arginine (R) at amino acid position 874 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
