Have you made a baby anterior deafness gene test?

The child was naughty, and after hearing a slap in the palm, he couldn’t hear it; when he was born, he had a good hearing. After a vaccine, he suddenly fell awkward… Most of the cases were considered accidents or accidents, but have you ever thought about it? Is it caused by a defect in the deafness gene that the child has?

Experts said that there is60%The deafness is related to genetic factors. The detection of deafness genes can predict in advance whether the baby carries the deafness gene and avoid the occurrence of hereditary deafness. In the case of deafness, the hearing aid can be fitted or cochlear implant at the best time. To avoid dumbness caused by cockroaches.

Parents with normal hearing also have deafness baby

According to statistics, in the defects of newborns, congenital deafness is in the forefront.

They may be carriers of deafness genes. They do not have their own disease, but they will pass the disease-causing gene to the next generation and cause the child to become ill. ”

It is understood that the common cariogenic genes in the Chinese population areGJB2,GJB3,SLC26A4AndmtDNA. Deafness caused by mutations in these four genes, accounting for the entire genetic deafness60%. Therefore, as long as you grasp these four genes, you can basically find the cause of most deafness.

In addition, due to the opening of the second child policy, the possibility of mutations in many older parents’ genes is also It is very important to carry out deafness gene detection in advance.
