Genes affected

FRS3 (HGNC:16970): (fibroblast growth factor receptor substrate 3) This gene encodes a substrate for the fibroblast growth factor receptor. The encoded protein is found in the peripheral plasma membrane and links fibroblast growth factor receptor stimulation to activators of Ras. The encoded protein down-regulates extracellular regulated kinase 2 through direct binding. [provided by RefSeq, Jul 2013]

Collection Method:clinical testing

The c.670C>T (p.R224W) alteration is located in exon 7 (coding exon 5) of the FRS3 gene. This alteration results from a C to T substitution at nucleotide position 670, causing the arginine (R) at amino acid position 224 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
