Genes affected

RSU1 (HGNC:10464): (Ras suppressor protein 1) This gene encodes a protein that is involved in the Ras signal transduction pathway, growth inhibition, and nerve-growth factor induced differentiation processes, as determined in mouse and human cell line studies. In mouse, the encoded protein was initially isolated based on its ability to inhibit v-Ras transformation. Multiple alternatively spliced transcript variants for this gene have been reported; one of these variants was found only in glioma tumors. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.5C>G (p.S2C) alteration is located in exon 2 (coding exon 1) of the RSU1 gene. This alteration results from a C to G substitution at nucleotide position 5, causing the serine (S) at amino acid position 2 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
