Genes affected
CMTM5 (HGNC:19176): (CKLF like MARVEL transmembrane domain containing 5) This gene encodes a member of the chemokine-like factor superfamily. This family of genes encodes multi-pass membrane proteins that are similar to both the chemokine and the transmembrane 4 superfamilies of signaling molecules. The encoded protein may exhibit tumor suppressor activity. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 09, 2024The c.238C>G (p.Q80E) alteration is located in exon 2 (coding exon 2) of the CMTM5 gene. This alteration results from a C to G substitution at nucleotide position 238, causing the glutamine (Q) at amino acid position 80 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
