Genes affected

TMEFF2 (HGNC:11867): (transmembrane protein with EGF like and two follistatin like domains 2) This gene encodes a member of the tomoregulin family of transmembrane proteins. This protein has been shown to function as both an oncogene and a tumor suppressor depending on the cellular context and may regulate prostate cancer cell invasion. Multiple soluble forms of this protein have been identified that arise from both an alternative splice variant and ectodomain shedding. Additionally, this gene has been found to be hypermethylated in multiple cancer types. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2015]

The c.916A>G (p.S306G) alteration is located in exon 9 (coding exon 9) of the TMEFF2 gene. This alteration results from a A to G substitution at nucleotide position 916, causing the serine (S) at amino acid position 306 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
