BSPRY

Chr 9

B-box and SPRY domain containing

The BSPRY protein is predicted to function as a ubiquitin protein ligase involved in innate immune responses and may regulate epithelial calcium transport by inhibiting TRPV5 channel activity. Mutations in BSPRY cause autosomal recessive spastic paraplegia and developmental delay. The gene shows low constraint against loss-of-function variants, consistent with a 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.

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.
