The deaf person in Beijing 14 carries and causes the deaf gene
It is reported ' Reporter Wang Dan) On December 7, the high-risk group in Beijing cause the deaf gene to sift checking the project measures the result to release. Expert say result this examine for deaf person and their family deaf preventing deaf work from establish the foundation not merely, there are important meanings on preventing nationwide deaf prevention and control such as the neonatal inborn defect.

It is introduced, this project is jointly launched by departments such as Beijing Association for the Handicapped, health bureau,etc., have held to the card deaf person and carried on gathering and laboratory detection of blood specimen to 20839 of 16 districts, counties of this market, the crowd covers Beijing and holds the card deaf person's 97% to sift checking. Among them, 2970 people are detected and carried and cause the deaf gene, therefore calculation, the detection rate of average gene mutation reaches 14.3%. In sifting 0~7 deaf year old that check, the children up to 43% carry heredity and cause the deaf gene, the heredity of colony of deaf person under the age of 40 causes the carrying rate of deaf gene to reach 30.4%.

Deaf the intersection of disease and member, expert of project team and general hospital of PLA diagnose Dai Pu Professor, director of centre, say, according to sifting and checking the result, can implement corresponding preventing and intervening the tactics deafly to different age stage crowds. For example, for making a definite diagnosis of the infant deaf for heredity, can avoid a large number of unnecessary inspections, through guiding its behavior pattern, slowing down residual hearing drops intensity and speed; As to the deaf crowd of the breeding time, can be under the scientific interference of deafness genetic diagnosis and pre-natal diagnosis, ensure the offspring married couple with clear hereditary risk not to will not bear the deaf offspring.

Sift, check result reveal 442 people carry the intersection of medicine and sensitiveness, cause deaf relevant mitochondrial gene mutation still. Dai Pu says, according to the maternal hereditary law, the maternal family members of about 10 multiple purposes, namely more than 4000 people will change suddenly to carry the gene. Though the above-mentioned crowd has normal hearing at present, once misapply amino sugar glucoside medicine such as gentamicin, can cause deafly. Sift checking the result can put forward prewarning to the above-mentioned crowd this time. In addition, all sieves find that carry the individual of gene mutation, the hereditary risk of deafness at various degrees exists to brief on its family.
