Genes affected

MCF2L (HGNC:14576): (MCF.2 cell line derived transforming sequence like) This gene encodes a guanine nucleotide exchange factor that interacts specifically with the GTP-bound Rac1 and plays a role in the Rho/Rac signaling pathways. A variant in this gene was associated with osteoarthritis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2016]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.416C>T (p.T139M) alteration is located in exon 5 (coding exon 5) of the MCF2L gene. This alteration results from a C to T substitution at nucleotide position 416, causing the threonine (T) at amino acid position 139 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
