CLEC12B

Chr 12

C-type lectin domain family 12 member B

Also known as: UNQ5782

Enables protein phosphatase binding activity and signaling receptor inhibitor activity. Involved in several processes, including melanocyte proliferation; natural killer cell inhibitory signaling pathway; and regulation of signal transduction. Located in external side of plasma membrane. Part of protein-containing complex. [provided by Alliance of Genome Resources, Jul 2025]

This gene has evidence for multiple mechanisms of pathogenicity (dominant-negative and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to dominant-negative as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.

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.
