UNC93A
Chr 6unc-93 homolog A
Also known as: Unc-93A, dJ366N23.1, dJ366N23.2
UNC93A encodes a plasma membrane protein with unknown specific function. Mutations cause autosomal recessive developmental and epileptic encephalopathy with onset in infancy, characterized by severe seizures, developmental delay, and brain abnormalities. The gene shows minimal constraint against loss-of-function variants, consistent with recessive inheritance where heterozygous carriers are unaffected.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Tolerant to missense variation
The highest-scoring mechanism for this gene is dominant-negative.
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.
