SLC15A5
Chr 12solute carrier family 15 member 5
The protein functions as a proton oligopeptide cotransporter that transports small peptides across cellular membranes. Mutations cause autosomal recessive developmental and epileptic encephalopathy with microcephaly, which typically presents in early infancy with seizures, developmental delay, and reduced head circumference. This gene shows minimal constraint against loss-of-function variants in population databases.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Mild missense constraint
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.
