A number sign (#) is used with this entry because of evidence that autosomal recessive deafness-35 (DFNB35) is caused by homozygous mutation in the ESRRB gene (602167) on chromosome 14q24.
Ansar et al. (2003) described a large consanguineous 6-generation Pakistani kindred segregating autosomal recessive nonsyndromic, nonprogressive prelingual deafness.
By linkage analysis using DNA samples from 24 members of a Pakistani family segregating autosomal recessive nonsyndromic deafness, Ansar et al. (2003) mapped the phenotype, termed DFNB35, to a 17.54-cM region on chromosome 14 flanked by markers D14S57 and D14S59. Haplotype examination revealed an 11.75-cM homozygous region between markers D14S588 and D14S59. A maximum 2-point lod score of 5.3 and a multipoint lod score of 7.6 were obtained at marker D14S53.
In a large consanguineous family of Turkish origin, Collin et al. (2008) used genomewide homozygosity mapping to reveal a locus for recessive nonsyndromic hearing impairment on chromosome 14q24.3-q34.12. Fine mapping with microsatellite markers defined the critical linkage interval to a 18.7-cM region flanked by markers D14S53 and D14S1015. This region partially overlapped with the DFNB35 locus.
Collin et al. (2008) performed mutation analysis of ESRRB, a candidate gene in the DFNB35 overlapping critical region, and detected a homozygous 7-bp duplication in exon 8 (602167.0001) in all affected individuals of a consanguineous Turkish family. The original family described by Ansar et al. (2003) carried a missense mutation (V342L; 602167.0003). In 3 other DFNB35-linked consanguineous families from Pakistan 3 different homozygous ESRRB missense mutations were found. One of the missense mutations (A110V; 602167.0002) was located in the DNA-binding domain of the estrogen-related receptor-beta protein, whereas the other 3 missense mutations were located in the ligand-binding domain. Molecular modeling of this nuclear receptor showed that the missense mutations were likely to affect the structure and stability of these domains. These and other data indicated that ESRBB is essential for inner ear development and function. This was thought to be the first report of pathogenic mutations of an estrogen-related receptor gene.
In a consanguineous Pakistani family (DEM1400) with congenital deafness, originally studied by Santos et al. (2006) and mapped to the DFNB68 locus (see 610419), Santos-Cortez et al. (2016) found no mutation in the S1PR2 gene (605111) but did identify a putatively pathogenic variant in the ESRRB gene (c.690delT, Gly231ValfsTer10, NM_004452.3) for which 4 of 5 affected individuals were homozygous. The mutation was predicted to initiate nonsense-mediated decay and was not found in 174 Pakistani controls, in 76 in-house exomes, or in the ExAC database. The fifth affected individual, who had profound hearing loss by audiometry, was heterozygous for the mutation; the authors noted that his deafness might be due to some other genetic or environmental cause.
