Genes affected

CMTM1 (HGNC:19172): (CKLF like MARVEL transmembrane domain containing 1) This gene belongs to the chemokine-like factor gene superfamily, a novel family that is similar to the chemokine and the transmembrane 4 superfamilies of signaling molecules. The protein encoded by this gene may play an important role in testicular development. Alternatively spliced transcript variants encoding different isoforms have been identified. Naturally occurring read-through transcription occurs between this locus and the neighboring locus CKLF (chemokine-like factor).[provided by RefSeq, Feb 2011]

CMTM1 links:

CKLF-CMTM1 (HGNC:39977): (CKLF-CMTM1 readthrough) This locus represents naturally occurring read-through transcription between the neighboring CKLF (chemokine-like factor) and CMTM1 (CKLF-like MARVEL transmembrane domain containing 1) genes on chromosome 16. The read-through transcript produces a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Feb 2011]

The c.283A>G (p.T95A) alteration is located in exon 1 (coding exon 1) of the CMTM1 gene. This alteration results from a A to G substitution at nucleotide position 283, causing the threonine (T) at amino acid position 95 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
