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]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 05, 2023The c.13C>T (p.H5Y) alteration is located in exon 1 (coding exon 1) of the CMTM1 gene. This alteration results from a C to T substitution at nucleotide position 13, causing the histidine (H) at amino acid position 5 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
