Genes affected
CMTM3 (HGNC:19174): (CKLF like MARVEL transmembrane domain containing 3) 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. This gene is one of several chemokine-like factor genes located in a cluster on chromosome 16. Alternatively spliced transcript variants containing different 5' UTRs, but encoding the same protein, have been identified. [provided by RefSeq, Jul 2008]
CMTM4 (HGNC:19175): (CKLF like MARVEL transmembrane domain containing 4) 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. This gene is one of several chemokine-like factor genes located in a cluster on chromosome 16. Alternatively spliced transcript variants encoding different isoforms have been identified.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.422T>C (p.I141T) alteration is located in exon 5 (coding exon 4) of the CMTM3 gene. This alteration results from a T to C substitution at nucleotide position 422, causing the isoleucine (I) at amino acid position 141 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
