The protein is essential for normal spermatogenesis and male fertility, specifically required for sperm head morphology, acrosome formation and attachment, and facilitating acrosome biogenesis through Golgi-derived vesicle formation and fusion. Biallelic mutations cause spermatogenic failure with autosomal recessive inheritance. This gene shows low constraint against loss-of-function variants in the general population.

Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
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.
