Perrault syndrome 5 is a rare autosomal recessive disorder that characterized by the association of sensorineural hearing loss and ovarian dysgenesis in females with diversity neurologic deficits due to variants twinkle mtDNA helicase (<i>TWNK</i>) gene. Since develop gradually, patient often misdiagnosed other neurological disease during early age. Herein, we report case geneticall...
BACKGROUND Audiological evaluation of parents of individuals with autosomal recessive hearing loss. AIM To study the audiological profile of parents of individuals with autosomal recessive hearing loss, inferred by family history or by molecular tests that detected heterozygous mutations in the GJB2 gene. This gene codes Connexin 26. METHOD Participants were 36 subjects, ranging between 30 ...
Introduction: Hearing loss is the most common sensory neural defect in humans, affecting 1 in 1000 neonates, with over half of these cases predicted to be hereditary in nature. Most hereditary hearing loss is inherited in a recessive fashion, accounting for approximately 80 % of non-syndromic hearing loss (NSHL). Mutations in GJB2 gene are major cause of inherited deafness in the European an...
sensorineural non-syndromic hearing loss is the most common disorder which affects 1 in 500 newborns. hearing loss is an extremely heterogeneous defect with more than 100 loci identified to date. according to the studies, mutations in gjb2 are estimated to be involved in 50- 80% of autosomal recessive non-syndromic hearing loss cases, but contribution of other loci in this disorder is yet ambig...
Mutations in the GJB2 gene encoding connexin26 (CX26) account for up to 50% of cases of autosomal recessive hearing loss. In contrast, only one GJB2 mutation has been reported to date in an autosomal dominant form of isolated prelingual hearing loss. We report here a novel heterozygous 605G-->T mutation in GJB2 in all affected members of a large family with late childhood onset of autosomal dom...
Mutations in the GJB2 gene, encoding connexin 26 (Cx26), are a major cause of nonsyndromic recessive hearing loss in many countries. We report here on a novel point mutation in GJB2, p.L76P (c.227C>T), in compound heterozygosity with a c.35delG mutation, in two Brazilian sibs, one presenting mild and the other profound nonsyndromic neurosensorial hearing impairment. Their father, who carried a ...

Mutations in the estrogen-related receptor beta (ESRRB) gene is the underlying cause of autosomal recessive nonsyndromic hearing impairment (ARNSHI) due to the DFNB35 locus which maps to 14q24.3. A genome scan of a large consanguineous Pakistani pedigree with ARNSHI established linkage with a maximum multipoint LOD score of 4.2 to the 14q24 region and the region of homozygosity contained the ES...
The molecular basis for autosomal dominant progressive nonsyndromic hearing loss in an Israeli Jewish family, Family H, has been determined. Linkage analysis placed this deafness locus, DFNA15, on chromosome 5q31. The human homolog of mouse Pou4f3, a member of the POU-domain family of transcription factors whose targeted inactivation causes profound deafness in mice, was physically mapped to th...
