The Cause of Hereditary Hearing Loss in GJB2 Heterozygotes-A ...

WebHearing loss can be due to a pathogenic variant in GJB2 gene paired with a deletion of the GJB6 gene. This form of inheritance is called “Digenic or double heterozygosity” because pathogenic variants in two different genes cause the condition in one individual. WebThe GJB2 gene provides instructions for making a protein called gap junction beta 2, more commonly known as connexin 26. Connexin 26 is a member of the connexin protein family. Connexin proteins form channels called gap junctions that permit the transport of nutrients, charged atoms (ions), and signaling molecules between adjoining cells. sma distributionWebHearing loss that results from changes in the middle ear is called conductive hearing loss. ...
