Genes affected

CMTM7 (HGNC:19178): (CKLF like MARVEL transmembrane domain containing 7) This gene belongs to the chemokine-like factor gene superfamily, a novel family that is similar to the chemokine and transmembrane 4 superfamilies. This gene is one of several chemokine-like factor genes located in a cluster on chromosome 3. This gene acts as a tumor suppressor that regulates G1/S transition in the cell cycle, and epidermal growth factor receptor/protein kinase B signaling during tumor pathogenesis. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Feb 2016]

The c.304G>A (p.V102M) alteration is located in exon 2 (coding exon 2) of the CMTM7 gene. This alteration results from a G to A substitution at nucleotide position 304, causing the valine (V) at amino acid position 102 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
