This gene encodes a serine protease that hydrolyzes specific peptide substrates with a preference for arginine residues. Biallelic mutations cause autosomal recessive nonsyndromic hearing loss (DFNB95), typically presenting as congenital or early-onset sensorineural hearing impairment. The gene shows minimal constraint against loss-of-function variants in population databases.

Population Constraint (gnomAD)
Low constraint (pLI 0.00) — loss-of-function variants are relatively tolerated in the population.

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.
