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 GeneticsSep 12, 2023The c.82G>A (p.A28T) alteration is located in exon 2 (coding exon 1) of the TRPM8 gene. This alteration results from a G to A substitution at nucleotide position 82, causing the alanine (A) at amino acid position 28 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
