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.2338A>G (p.I780V) alteration is located in exon 23 (coding exon 22) of the MCF2 gene. This alteration results from a A to G substitution at nucleotide position 2338, causing the isoleucine (I) at amino acid position 780 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
