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]

The c.729A>T (p.K243N) alteration is located in exon 8 (coding exon 7) of the RSU1 gene. This alteration results from a A to T substitution at nucleotide position 729, causing the lysine (K) at amino acid position 243 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
