Description

Among 28 unrelated Spanish families with nonsyndromic sensorineural hearing loss (601071), Migliosi et al. (2002) identified 1 family with a mutation in the OTOF gene: a 2485C-T transition in exon 22, resulting in a premature stop codon, gln829 to ter (Q829X). Both parents were carriers of the mutation and their 2 affected children were homozygous. The mutation was not present in 200 unrelated Spanish controls with normal hearing. Genetic analysis of another 269 unrelated patients with hearing loss revealed 11 more cases (8 sporadic and 3 familial) of the Q829X mutation. One of these families was compound heterozygous for Q829X and P1825A (603681.0005). Migliosi et al. (2002) determined that the Q829X mutation was responsible for 4.4% of recessive familial or sporadic cases of deafness in the Spanish population, and presented evidence for a founder effect.

Varga et al. (2006) found the Q829X mutation in 2 families. They referred to Q829X as the Hispanic mutation, it having been found in a group of Spanish families and 1 Cuban family as noted. They described it in a family from England with no known Hispanic ancestry. In a family of Mexican ancestry, the Q829X mutation was present in heterozygous state.
