Genes affected
TRPM8 (HGNC:17961): (transient receptor potential cation channel subfamily M member 8) Predicted to enable ligand-gated calcium channel activity. Predicted to be involved in calcium ion transmembrane transport and positive regulation of cold-induced thermogenesis. Predicted to act upstream of or within several processes, including cellular calcium ion homeostasis; response to cold; and thermoception. Located in plasma membrane.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2024The c.635T>C (p.I212T) alteration is located in exon 6 (coding exon 5) of the TRPM8 gene. This alteration results from a T to C substitution at nucleotide position 635, causing the isoleucine (I) at amino acid position 212 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
