Gene mutation causes old listening recession

Technology channels () message: Netherlands researchers study shows, audition recession after middle age and a specific gene mutations.

Study in the United Kingdom 61-70 of about 37%, 70-80-year-old man in approximately 60% (650 million people) suffer from age-related hearing recession. United Kingdom human mutation Association for 1200 people, a study found that a gene called KCNQ4 subtle changes occur in those aged patients with hearing problems become more popular. United Kingdom Royal deaf agencies funded the study, the Agency said it is treating hearing recession provides "real" hope.

KCNQ4 gene mutations and hereditary hearing recession, recession of hereditary hearing loss will occur.

Antwerp University research groups want to understand whether smaller KCNQ4 gene changes can also affect the age-related hearing recession. The research group on 1200 men aged 40-80 participants in between. Researcher first tested the participants of the hearing, then their DNA testing. The researchers found that gene mutations in three — DNA in called SNPs (single nucleotide polymorphisms, SNPs) of a single nucleotide resulting difference — in patients with hearing recession was found in DNA, but in the hearing person's DNA but did not find in this change.

They said that now is also a need for more research to determine these genetic errors on hearing what effect. They summarize the possible explanations include, contributed to the hair cells in the formation of potassium, or cause its migration too fast.

United Kingdom Royal National Institute for deaf people (RNID) biomedical research leader Dr. Ralph · kholmy said: "many people think that hearing loss is inevitable in the aging process, and not see it as a potentially preventable conditions. This research is to highlight the gene and senile links between listening recession provides another important evidence. At this moment, we can do nothing about it. People can wear a hearing aid, but this does not prevent their listening recession. This study has provided us with an exact wishes to prevent age-related hearing recession treatments will be found, and we are convinced that future with age, people will no longer need to face the threat of recession in the hearing. ”
