Facio Auricular Vertebral (FAV) or Goldenhar syndrome is a very rare kind of syndromic deafness and is inherited as autosomal dominant. A study was taken up to understand the prevalence of this syndrome in children below the age of 14 years with hearing loss. Out of 1073 children with hearing impairment, Goldenhar syndrome was observed only in 1 (0.09%) case. The child suffered severe hearing l...

OBJECTIVE We present a patient with mitochondrial hearing loss and a novel mitochondrial DNA transition, who underwent successful cochlear implantation. CASE REPORT An 11-year-old girl showed epilepsy and progressive hearing loss. Despite the use of hearing aids, she gradually lost her remaining hearing ability. Laboratory data revealed elevated lactate levels, indicating mitochondrial dysfun...

Mutations in Gap Junction Beta 2 (GJB2) have been reported to be a major cause of non-syndromic hearing loss in many populations worldwide. The spectrums and frequencies of GJB2 variants vary substantially among different ethnic groups, and the genotypes among these populations remain poorly understood. In the present study, we carried out a systematic and extended mutational screening of GJB2 ...

MYO15A is the third most crucial gene in hereditary sensorineural hearing loss after GJB2 and SLC26A4. In the present study, we reviewed the prevalence of MYO15A mutations in patients with autosomal recessive non-syndromic hearing loss (ARNSHL). In this meta-analysis, we conducted a search of PubMed, Web of Science, Excerpta Medica Database, and Scopus, and identified the articles up to Septemb...

Objectives Targeted next-generation sequencing (NGS) provides a consequential opportunity to elucidate genetic factors in known diseases, particularly in profoundly heterogeneous disorders such as non-syndromic hearing loss (NSHL). Hearing impairments could be classified into syndromic and non-syndromic types. This study intended to assess the significance of mutations in these genes to the aut...
