My parents have poor hearing, and so do I. Will I pass it on to my children in the future?
Congenital hearing loss may be passed on to the next generation, while acquired hearing loss is usually not passed on to the next generation. It is recommended that patients with hearing loss go to the hospital in time to check for external factors and prepare for pregnancy.
There are many causes of hearing impairment, some are not hereditary, and some are hereditary. Generally speaking, this kind of hearing impairment that is inherited is called hereditary deafness. Most of it is congenital. For example, the child is born with congenital deafness. At this time, we will do a genetic screening and find out that he It is indeed hereditary deafness. He is very likely to pass this gene to the next generation, causing the next generation to have this deafness. Others are not. Although they are born healthy, in fact, they also have the gene for hereditary deafness. Although they are healthy, if their spouse also carries this gene, it is a recessive inheritance, causing his next generation to also have the disease. Hereditary deafness may occur.
It is estimated that each of us has about 30,000 genes, which control our morphological characteristics, such as height, appearance, etc. These genes are passed from generation to generation in the family, and mutations may occur during the transmission process. Mutated genes can also be passed on. Some bad genes can cause diseases when passed on. Some of these genes control hearing, and if something goes wrong, it can lead to deafness. This type of deafness is called hereditary deafness. Among them, half of the causes of congenital deafness are related to genetics, that is, there is something wrong with the deafness gene, and the other half is related to environmental factors. For example, the mother is infected by certain viruses during pregnancy, or the child is born with severe jaundice or ischemia. Hypoxic encephalopathy, etc.
Some hearing parents who have already given birth to deaf children hope to give birth to the next generation with healthy hearing. After the cause of the deaf children in their families is clarified through genetic diagnosis, further treatment can be carried out. Prenatal diagnosis of the fetus in the mother's womb and prenatal guidance can prevent such families from giving birth to deaf children again.
