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.

Mar 16, 2022

The c.65G>A (p.R22Q) alteration is located in exon 1 (coding exon 1) of the CMTM6 gene. This alteration results from a G to A substitution at nucleotide position 65, causing the arginine (R) at amino acid position 22 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
