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 GeneticsMar 20, 2023The c.23G>A (p.R8Q) alteration is located in exon 1 (coding exon 1) of the CMTM5 gene. This alteration results from a G to A substitution at nucleotide position 23, causing the arginine (R) at amino acid position 8 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
