En los adultos desconocemos el porcentaje de hipoacusias hereditarias. The aim of this review is to provide conductivs updated overview of hereditary hearing loss, with special attention to the etiological diagnosis of sensorineural hearing loss, the genes most frequently mutated in our environment, the techniques available for their analysis and the clinical implications of genetic diagnosis.

In adults, the percentage of hereditary hearing conudctiva is unknown. Genetic testing is the highest yielding test for evaluating patients with sensorineural hearing loss. The process of genetic counselling is intended to inform patients and their families of the medical, psychological and familial implications of genetic diseases, as well as the risks, benefits and limitations of genetic testing.

The implementation of any genetic analysis must be always preceded by an appropriate genetic counselling process. Por lo tanto, los implantes cocleares suelen proporcionar un buen rendimiento en estos pacientes Por el contrario, las hipoacusias dominantes DFNA suelen ser poslinguales y progresivas. Sin embargo, existen numerosas excepciones a esta regla.

Cuando estos canales se agrupan dan lugar a las denominadas uniones tipo hendidura gap junctions. Estos pacientes se denominan heterocigotos compuestos. Puesto que el nervio auditivo funciona correctamente, los implantes cocleares en pacientes con mutaciones en el gen OTOF proporcionan un rendimiento similar al obtenido en otras hipoacusias cocleares Esto puede ocurrir como consecuencia de la elevada prevalencia en nuestro medio de portadores de mutaciones en el gen GJB2.

Tanto las deleciones como las duplicaciones de los genes previamente mencionados pueden ocasionar hipoacusias hereditarias 51,90— Read this article in English.
