Genes affected

RHOD (HGNC:670): (ras homolog family member D) Ras homolog, or Rho, proteins interact with protein kinases and may serve as targets for activated GTPase. They play a critical role in muscle differentiation. The protein encoded by this gene binds GTP and is a member of the small GTPase superfamily. It is involved in endosome dynamics and reorganization of the actin cytoskeleton, and it may coordinate membrane transport with the function of the cytoskeleton. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2014]

The c.503A>G (p.Y168C) alteration is located in exon 5 (coding exon 5) of the RHOD gene. This alteration results from a A to G substitution at nucleotide position 503, causing the tyrosine (Y) at amino acid position 168 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
