Genes affected

RASSF3 (HGNC:14271): (Ras association domain family member 3) The RAS oncogene (MIM 190020) is mutated in nearly one-third of all human cancers. Members of the RAS superfamily are plasma membrane GTP-binding proteins that modulate intracellular signal transduction pathways. A subfamily of RAS effectors, including RASSF3, share a RAS association (RA) domain.[supplied by OMIM, Jul 2003]

Collection Method: clinical testing

The c.655C>T (p.R219C) alteration is located in exon 5 (coding exon 5) of the RASSF3 gene. This alteration results from a C to T substitution at nucleotide position 655, causing the arginine (R) at amino acid position 219 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
