Hearing loss that precedes the onset of speech or learning spoken language; it is severe, stable, and less common than post-lingual hearing loss.
Aetiology Prelingual hearing loss is largely inherited: 50% are monogenic, 75% are autosomal recessive; 20%, autosomal dominant; 5%, X-linked recessive; the rest are caused by perinatal factors, infections in infancy or trauma

Mutations in TMPRSS3 have previously been described to cause autosomal recessive progressive hearing impairment with postlingual onset (DFNB8) as well as severe-to-profound prelingual hearing impairment (DFNB10).
In autosomal recessive, the first locus DFNB1 (Cx26 gene) was identified in two Tunisian consanguineous families with bilateral profound prelingual hearing impairment (10).
