A number sign (#) is used with this entry because autosomal recessive deafness-6 (DFNB6) is caused by homozygous or compound heterozygous mutation in the transmembrane inner ear-expressed gene (TMIE; 607237) on chromosome 3p21.
Sirmaci et al. (2009) reported multiple Turkish families with autosomal recessive DFNB6 confirmed by genetic analysis. The phenotype consisted of congenital/prelingual onset of severe to profound sensorineural hearing loss without other features and without inner ear anomalies.
In a family with 3 deaf children out of 4 offspring of a second-cousin marriage, Fukushima et al. (1995) found homozygosity by descent in the parents for a region of chromosome 3p. From observations in the affected progeny, they located a new deafness locus, DFNB6, to a 14- to 20-cM interval bounded by D3S1619 and D3S1766; maximum LOD = 3.3. Petit (1996), who gave a comprehensive account of the various forms of genetic deafness that have been mapped, listed the location of the DFNB6 gene as chromosome 3p21-p14.
The TMIE gene (607237), located in the DFNB6 interval, is the human homolog of the mouse gene, Tmie, mutant in the 'spinner' phenotype (Mitchem et al., 2002). Therefore, Naz et al. (2002) performed a mutation screen of TMIE in affected individuals in families demonstrating linkage to the DFNB6 region. Five different homozygous recessive mutations (607237.0001-607237.0005) were identified in members of consanguineous families.
Sirmaci et al. (2009) found that the R84W mutation (607237.0003) was the most common mutation in the TMIE gene among Turkish families with autosomal recessive deafness. The frequency of the R84W mutation among families throughout Turkey with hearing loss who did not have GJB2 (121011) mutations was 3.1%, but increased to 12.2% in southeastern Anatolia. Haplotype analysis indicated that R84W was a founder mutation arising from a common ancestor approximately 1,250 years ago.
Petit (1996) listed the location of the DFNB6 gene as 3p21-p14 and suggested 'spinner' (sr) on mouse chromosome 9 as a putative mouse homolog. Mitchem et al. (2002) demonstrated 2 independent mutations in the Tmie gene as the cause of hearing loss and vestibular dysfunction in 'spinner' mice.
In an article published in January 1996, Chaib et al. (1996) used the symbol DFNB6 for a form of sensorineural nonsyndromic recessive deafness caused by mutation on chromosome 2p23-p22. The later described form is referred to here as DFNB9 (601071).
