SCIMP

Chr 17

SLP adaptor and CSK interacting membrane protein

Also known as: C17orf87, UNQ5783

The protein encoded by this gene functions as a transmembrane adaptor that scaffolds signaling proteins in immune cells, facilitating MHC class II signal transduction, toll-like receptor signaling, and immune synapse formation in antigen-presenting cells. Mutations in SCIMP cause autosomal recessive immunodeficiency with recurrent infections. The gene shows low constraint against loss-of-function variants, consistent with its recessive inheritance pattern.

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.

GOFprediction above median
DNprediction above median

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.
