| Chromosomal Location |
22q13.1 |
| Allelic Variant 1 |
609761.0004; DEAFNESS, AUTOSOMAL RECESSIVE 28 |
| Identified Mutation |
ARG788TER; In a Pakistani family, Riazuddin et al. (Am J Hum Genet 78:137-143, 2006) found a nonsense mutation, arg788 to stop (R788X), in exon 6 of the long isoform of TRIOBP as the cause of nonsyndromic recessive deafness (DFNB28; 609823). The mutation arose from a C-to-T transition at nucleotide 2362. |

| Remarks |
Clinically affected; hearing loss confirmed by audiometry; product of consanguineous marriage; two affected brothers; father is GM20184; donor subject is homozygous for a nonsense mutation: a C>T transion at nucleotide 2362 (2362C>T) in exon 6 of the long isoform of the TRIOBP gene, resulting in an Arg788 to stop [Arg788Ter (R788X)] |
