IllnessHearing loss, autosomal dominant; differential diagnosis

NGS +

[Sanger]

Hearing loss can present at any time from infancy to old age. More than half of the cases of pre-lingual hearing loss are genetic, and approximately 10% of these most frequent sensory deficits are inherited in an autosomal dominant manner (DFNA). In non-syndromic families with post-lingual deafness, dominant inheritance is twice as common. Nearly one-third of cases with hearing loss are associated with other symptoms, and approximately 600 such syndromes are known. Most forms of non-syndromic hearing loss are sensorineural with permanent hearing loss due to damage to inner ear structures; less commonly, conductive causes exist in the middle ear. Mutations in >50 genes have been identified in people with autosomal dominant non-syndromic hearing loss; mutations in some of these genes (GJB2, GJB6) may also cause autosomal recessive forms of the disease. Mutations in a few genes (e.g. KCNQ4, TECTA) occur more frequently. Mutations in many of the other genes have been found in only one or a few families. The overall diagnostic yield for hereditary hearing loss depends on the ethnic background of the patients with <50% in Europeans, Africans and North as well as South Americans. Studies in the Middle East showed >60% yield in some areas. A negative molecular genetic result excludes the clinical diagnosis by no means. Genetic testing, on the other hand, can identify subclinical or presymptomatic syndromes. This fact should be taken into account in education or counseling.
