LYZL1

Chr 10

lysozyme like 1

Also known as: KAAG648, LYC2, LYZD1, PRO1278, bA534G20.1

The protein is predicted to function as a lysozyme in the extracellular region, breaking down bacterial cell walls as part of innate immune defense. LYZL1 mutations cause teratozoospermia, characterized by abnormal sperm morphology leading to male infertility. The gene shows low constraint against loss-of-function variants, and the inheritance pattern for this condition has not been clearly established.

The Badonyi & Marsh model scores gain-of-function highest, but genomic evidence most strongly supports dominant-negative as the primary mechanism.

DNprediction above median

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.
