Genes affected
RHOQ (HGNC:17736): (ras homolog family member Q) This gene encodes a member of the Rho family of small GTPases, which cycle between inactive GDP-bound and active GTP-bound states and function as molecular switches in signal transduction cascades. Rho proteins promote reorganization of the actin cytoskeleton and regulate cell shape, attachment, and motility. The encoded protein is an important signalling protein for sarcomere assembly and has been shown to play a significant role in the exocytosis of the solute carrier family 2, facilitated glucose transporter member 4 and other proteins, possibly acting as the signal that turns on the membrane fusion machinery. Three related pseudogene have been identified on chromosomes 2 and 14. [provided by RefSeq, Aug 2011]

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.239T>C (p.M80T) alteration is located in exon 3 (coding exon 3) of the RHOQ gene. This alteration results from a T to C substitution at nucleotide position 239, causing the methionine (M) at amino acid position 80 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
