Abstract
Congenital hearing loss is one of the most common birth defects worldwide, with around
1 in 500 people experiencing some form of severe hearing loss. While over 400 different
syndromes involving hearing loss have been described, it is important to be familiar
with a wide range of syndromes involving hearing loss so an early diagnosis can be
made and early intervention can be pursued to maximize functional hearing and speech-language
development in the setting of verbal communication. This review aims to describe the
presentation and genetics for some of the most frequently occurring syndromes involving
hearing loss, including neurofibromatosis type 2, branchio-oto-renal syndrome, Treacher
Collins syndrome, Stickler syndrome, Waardenburg syndrome, Pendred syndrome, Jervell
and Lange-Nielsen syndrome, Usher syndromes, Refsum disease, Alport syndrome, MELAS,
and MERRF.
