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.29C>T (p.T10I) alteration is located in exon 1 (coding exon 1) of the CMTM7 gene. This alteration results from a C to T substitution at nucleotide position 29, causing the threonine (T) at amino acid position 10 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
