ESTUDO DE MUTAÇOES MITOCONDRIAIS ASSOCIADAS A DEFICIENCIA AUDITIVA SENSORIONEURAL EM PACIENTES BRASILEIROS

(especial para SIIC © Derechos reservados)
Muitas mutações podem contribuir para a presbiacusia e para a deficiência auditiva em geral, e a deleção mitocondrial mtDNA4977 associada a presbiacusia e a mutação mitocondrial A1555G relacionada ao uso de antibióticos aminoglicosídeos, podem ser apenas uma delas.

ESTUDO DE MUTAÇOES MITOCONDRIAIS ASSOCIADAS A DEFICIENCIA AUDITIVA SENSORIONEURAL EM PACIENTES BRASILEIROS

Resumen
Introdução: A presbiacusia é a causa mais comum de deficiência auditiva, geralmente associada ao envelhecimento e a mutação mitocondrial A1555G é a principal alteração associada a surdez ocasionada pelo uso de aminoglicosídeos. Objetivo: Investigar a prevalência da deleção mitocondrial de 4977 pares de bases em pacientes com presbiacusia e da mutação A1555G em neonatos. Material e métodos: Estudo de casos em cem pacientes com presbiacusia e em cem neonatos com audição normal. O DNA foi extraído de amostras de leucócitos e primers específicos foram designados para amplificar o gene do citocromo b e as regiões que abrangem a deleção de 4 977 pb e a mutação A1555G do DNA mitocondrial, usando a técnica da reação em cadeia da polimerase e do polimorfismo no comprimento de fragmentos de restrição. Resultados: Uma região do gene do citocromo b foi amplificada confirmando a presença do DNA mitocondrial em todas as amostras do estudo. A deleção mitocondrial mtDNA4977 não foi identificada em todos os pacientes com presbiacusia, assim como a mutação A1555G nos neonatos. Conclusões: Estes resultados não descartam a possibilidade da existência de outras mutações que possam ocasionar presbiacusia ou a deficiência auditiva associada ou não ao uso de aminoglicosídeos e reforçam a importância de se identificar as causas genéticas subjacentes a fim de propiciar melhor compreensão das doenças auditivas na população brasileira.

Study of Mitochondrial Mutations Associated with Sensorineural Hearing Loss in Brazilian Patients

Abstract
Introduction: Presbycusis -generally associated with aging- is the most frequent cause of hearing loss, and mitochondrial A1555G mutation is the main change associated with deafness caused by the use of aminoglycoside antibiotic. Objective: To investigate the prevalence of mitochondrial 4 977 bp deletion in patients with presbycusis and the prevalence of A1555G mutation in neonates. Material and methods: Case study on one hundred patients with presbycusis and one hundred neonates with normal hearing. DNA was extracted from leukocyte specimens and specific primers were designed to amplify cytochrome b gene and regions including mtDNA 4977 bp deletion and A1555G mutation, by PCR technique and restriction fragment length polymorphism (RFLP) technique. Results: A region of the cytochrome b gene was amplified and the presence of mtDNA was documented in all study specimens. Deletion of mtDNA4977 was not identified in any patient suffering from presbycusis, neither was A155G mutation found in neonates. Conclusions: These results do not allow ruling out the existence of other mutations causing presbycusis or hearing loss, associated or not with the use of aminoglycoside antibiotics, and to reinforce the importance of identifying the underlying genetic causes in order to contribute to a better understanding of hearing loss in the Brazilian population.
