biostudies-literatureUnknown13(5)Elmakhzen BGJB2 and GJB6 variants, encoding Cx26 and Cx30 respectively, are the most frequently involved genes commonly contributing to hereditary hearing loss either isolated or in combination with skin abnormalities. GJB6 variations are classically associated with two distinct conditions: non-syndromic hearing loss and hidrotic ectodermal dysplasia, type Clouston, the latter typically not involving deafness.<h4>Method</h4>Whole genome sequencing (WGS) was used to find genetic variants after clinical features of a 13-year-old female patient were recorded.<h4>Results</h4>In this report, we describe the association of congenital hearing loss and ectodermal anomalies (palmoplantar keratoderma, knuckle pads, and nail dystrophy) in a female with the ENST00000647029.1 (GJB6): c.175G>A (p.(Gly59Arg)) GJB6 Molecular genetics & genomic medicinee2474https://www.ebi.ac.uk/biostudies/studies/S-EPMC12078196biostudies-literatureA new syndromic case of hearing loss and ectodermal anomalies associated with a recurrent missense variation in GJB6 gene.PMC12078196Elmakhzen BGueguen PFajardy IGodey BRollier PLe Marechal CSaillard COdent SPasquier LfalseA new syndromic case of hearing loss and ectodermal anomalies associated with a recurrent missense variation in GJB6 gene.GJB2 and GJB6 variants, encoding Cx26 and Cx30 respectively, are the most frequently involved genes commonly contributing to hereditary hearing loss either isolated or in combination with skin abnormalities.
