SPATA20
Chr 17spermatogenesis associated 20
Also known as: HEL-S-98, SSP411, Tisp78
The protein is predicted to be involved in carbohydrate metabolism and cell differentiation and is located in mitochondria. Loss-of-function mutations in SPATA20 follow a de novo dominant inheritance pattern, though specific associated neurological diseases have not been established in the provided data. The extremely low pLI score suggests this gene is highly tolerant to loss-of-function variants.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Typical tolerance to LoF variation
Mild missense constraint
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.
