Genes affected
CMTM2 (HGNC:19173): (CKLF like MARVEL transmembrane domain containing 2) This gene belongs to the chemokine-like factor gene superfamily, a novel family that links the chemokine and the transmembrane 4 superfamilies of signaling molecules. The protein encoded by this gene may play an important role in testicular development. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 07, 2024The c.685C>A (p.P229T) alteration is located in exon 4 (coding exon 4) of the CMTM2 gene. This alteration results from a C to A substitution at nucleotide position 685, causing the proline (P) at amino acid position 229 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
