TRPM8

Chr 2

transient receptor potential cation channel subfamily M member 8

Also known as: LTRPC6, LTrpC-6, TRPP8, trp-p8

TRPM8 encodes a calcium-permeable ion channel that detects cold temperatures below 23-28°C and is activated by cooling compounds like menthol, playing a central role in environmental temperature sensing and basal tear secretion. Mutations cause autosomal dominant or recessive disorders affecting temperature sensation and potentially other sensory functions. The gene shows low constraint against loss-of-function variants, suggesting complete loss may be tolerated in some contexts.

The highest-scoring mechanism for this gene is gain-of-function.

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
