Genes affected

MCF2 (HGNC:6940): (MCF.2 cell line derived transforming sequence) The oncogenic protein encoded by this gene is a guanine nucleotide exchange factor (GEF) that exerts control over some members of the Rho family of small GTPases. Several transcript variants encoding different isoforms have been found for this gene. These isoforms exhibit different expression patterns and varying levels of GEF activity.[provided by RefSeq, Jan 2010]

The c.1709T>C (p.V570A) alteration is located in exon 16 (coding exon 15) of the MCF2 gene. This alteration results from a T to C substitution at nucleotide position 1709, causing the valine (V) at amino acid position 570 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
