Genes affected
CMTM6 (HGNC:19177): (CKLF like MARVEL transmembrane domain containing 6) This gene belongs to the chemokine-like factor gene superfamily, a novel family that is similar to the chemokine and transmembrane 4 superfamilies. This gene is one of several chemokine-like factor genes located in a cluster on chromosome 3. This gene is widely expressed in many tissues, but the exact function of the encoded protein is unknown.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 02, 2024The c.49C>A (p.P17T) alteration is located in exon 1 (coding exon 1) of the CMTM6 gene. This alteration results from a C to A substitution at nucleotide position 49, causing the proline (P) at amino acid position 17 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
