CLEC7A

Chr 12AR

C-type lectin domain containing 7A

Also known as: BGR, CANDF4, CD369, CLECSF12, DECTIN1, SCARE2

The protein functions as a pattern recognition receptor that recognizes beta-1,3-linked and beta-1,6-linked glucans from fungi, activating innate immune responses through NF-kappa-B and MAP kinase signaling pathways. Mutations cause autosomal recessive susceptibility to aspergillosis and familial candidiasis type 4, reflecting impaired antifungal immunity. The gene shows extremely low constraint against loss-of-function variants (pLI near zero), consistent with recessive inheritance where heterozygous carriers are typically unaffected.

This gene has evidence for multiple mechanisms of pathogenicity (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function 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.
