    This paper aims to present a third world case of Non-Syndromic sensorineural hearing loss (NSHL) due to a novel missense variant in COL11A1 gene, defined as DFNA37 non-syndromic hearing loss. The clinical features of a 6-year-old boy affected by a bilateral moderate to severe down-sloping sensorineural hearing loss are presented, as well as the genetic analysis, the latter identifying a heterozygous missense variation in the COL11A1 gene. In addition, in families with autosomal dominant transmission, COL11A1 gene should be considered in the genetic workup of the NSHL with prelingual onset.
