Mutations in GJB2 in patients with non-syndromic deafness

Note: since it would be of interest to keep a consensus on the name of the mutations in GJB2, we propose that all new mutations are named following the nomenclature recommendations (Antonarakis and the nomenclature working group (1998)), which indicate that in the case of a deletion or an insertion in a repeated sequence, the most 3' position should be adopted.
