Genes affected

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.

Ambry Genetics

Nov 29, 2023

The c.539G>A (p.R180H) alteration is located in exon 4 (coding exon 4) of the CMTM4 gene. This alteration results from a G to A substitution at nucleotide position 539, causing the arginine (R) at amino acid position 180 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
