A total of 35 patients from 20 families have been included in the study. The patient's DNA was isolated from peripheral blood samples. The GJB2 gene coding region was analyzed through Sanger sequencing.<\/jats:p><jats:p>\n          Results\u2003There is no changes in the first exon of the GJB2 gene. Nine different variants were recorded in second exon of the targeted gene. W24X and W77X are two nonsense mutations and three polymorphisms viz. R127H, V153I, and I33T were reported along with four 3\u2032-UTR variants. A total (9\/20) of 45% of families have been identified with mutations in the targeted gene.<\/jats:p><jats:p>\n          Conclusion\u2003GJB2 mutations were identified in 19 deaf-mute patients (19\/35), and 13 patients were homozygous for the mutations identified in our study cohort. In our study, W24X mutation was found to be the pathogenic with a high percentage, prompting further evaluation of the other genes, along with the study of additional genetic or external causes in the families, which is essential.<\/jats:p>","DOI":"10.1055\/s-0042-1743257","type":"journal-article","created":{"date-parts":[[2022,2,22]],"date-time":"2022-02-22T00:17:43Z","timestamp":1645489063000},"page":"152-158","source":"Crossref","is-referenced-by-count":3,"title":["Analysis of Genetic Variations in Connexin 26 (GJB2) Gene among Nonsyndromic Hearing Impairment: Familial Study"],"prefix":"10.1016","volume":"09","author":[{"given":"Smita","family":"Hegde","sequence":"additional","affiliation":[{"name":"Human Genetics Laboratory, Department of Anatomy, Shri B.M.
