别让孩子活在无声世界,对于先天性耳聋你一定要知道这些...“Congenital deafness”As the name, there is a hearing barrier in a baby birth.,It has been found to cause congenital deafness in the clinic mainly genetic factors.,Therefore, it is a key point to prevent it.,So in order not to let the baby born“Silent world”,For congenital deafness, you must know these!
Congenital deafnesswhat is the reason
What is congenital deafness?
Congenital deafness is a process of parent pregnancy、Deafness caused by abnormal or genetic factors during childbirth,Most of the emotional deafness。
Most congenital deaf patients have been hidden by chromosome,Probability75%,Instead of genetic congenital deafness20%。
Congenital deafness clinical manifestations
Congenital deafness is present in birth or shortly after birth,Hearing obstacles already existing。
Parents have congenital deafness,Will be a big possibility to generate congenital deafness to children。
Congenital deafness
Mother pregnancy3Month is the key period of fetal internal ear development,If the mother is cold during this period、Rapu and other viruses or syphilis infections,It is possible to prevent normal development of fetal internal ear.,Congenital hearing loss。
also,Mother's pregnancy, various poisoned diseases,Diabetes、Nephritis、Thyroid function is abnormal、abdomenXLine irradiation、Long-term depth anesthesia、Various poisoned drugs、Threatened abortion, etc.,It may also affect the fetal internal ear development。also,Neonatal serious jaundice、Hemolysis、Mother and childRhFactors can also cause neonatal listening losses。
Nearly married,Because couples have the same opportunity to have the same deductible gene,The incidence of hereditary listening loss is also relatively increased。Herble losses of hereditary deafness can appear during birth,It is also possible to gradually be clear.。
Congenital deafness
Congenital deafness segmentation genetic and non-genetic deafness,The former is mainly caused by chromosome defects,The latter is mostly by the drug/germ/Virus/Disease caused by disease。This article only discusses hereditary deafness。
Causes of congenital deafness
Hereditary deafness、Transduction deaf caused by middle ear development deformity,There is also a sensational neuropathy caused by inner ear development.,Among them, it is most important to emotional neurops.。Some causes:
1.Demonstrative hereditary:Genetic genes are located on a commonly stained chromosome、Genetic inheritance controlled by doant gene,As long as there is a genetic pass to the child,The child demonstrates the same deafness as the parents.,Demonstrative hereditary。
2.Dempected heritage:The deafening genes with a parent-based、Genetic inheritance controlled by doant gene,Only when the gene is paired in the homogenic,Deafness can show it。
3.Sexual chain genetic:due toYChromosome does not carry a complete allele,The pathogenic gene is in the sex chromosomeXChromosome,Be calledXChain genetic hidden deafness。
Under normal circumstances,Two people have a complete opportunity for the same deductible genes.。And the same blood,The likelihood of its gene is greatly increased,Therefore, nearer marriage can increase genetic morbidity。There are many types of genetic deafness,The onset time may be congenital,It may also be delayed。Usually doated genetic deafness is progressive,And hidden genetic deafness is not carried out。
Genetic deafness
Hereditary deafness mainly hidden、Doance、XConnecting chromosome genetic and mitochondrial maternal genetic way。
(1)Demonstrative helicy inheritance is the most common way in which,About hereditary deafness80%about。This genetic method is characterized by the parents may have a normal hearing.,However, carry a single recessive mutation(Carrier)。In their descendants,If the child has obtained two genetic mutations carried by parents from their parents,It is very likely that hereditary deafness is generated.。
(2)Demonstrative hereditary deafness is often genetically deafening15%about。Contrary to hidden hereditary deafness,The characteristics of doant hereditary deafness are that patients can lead to deafness as long as they carry a single doant genetic mutation.,The patient's parents and more the ancestors often have deafen patients,Family history is more obvious。
(3)XThe ratio of the genetic and mitochondrial maternal genetic in chain chromosome is relatively low.,Only hereditary deafness2-3%。But compared to other countries and people,Mitochondrial gene mutationA1555GRelatively be more common in the Chinese population。
Congenital deafness treatment
Clinical,recommend5Surgical treatment for cochlear implantation before years ago,Postoperative cooperation and speech training,Can improve the patient's listening situation。At present, domestic technology is mature in this area.。
Congenital deafness of fertility intervention
Congenital deafness is mostly emotional neuropathy,Therefore, it should be prevention。Vigorously promote eating,No close relatives;Strengthen genetic consultation,Popularity of influenic drug knowledge。If you want to completely avoid the congenital deafness to give the next generation,Consider prenating prenatal diagnosis to prevention。But more reliable method,If you want to completely block the genetic gene to the next generation,So you can consider the third test tube baby(PGD)Technology can be solved。
Embryonic implanted genetic diagnosis is also commonly known as three generations of test tube infant technology,AbbreviationPGD。It is an embryonic in vitro by helping reproductive technology.,Gene detection is then performed on these embryos,Choose embryonic implantation that is not carried with a pathogenic gene,To avoid the rebirth of these pathogenic genes。This technology is earlier than a prenatal diagnosis,Avoid prenating that the abnormal abnormal abnormal abnormalities in the fetus requires abortion or induction of labor。
According to the statistics,Every year in my country3.5Wan's newborn was taken to hearing before birth,Plus delay and drug deaf children,This number reached6Universal。And most people think“Only deafness will have a deaf person”。
But clinical data display,80%The parents of the deaf are normal.。100A hearing normal person,There is4-5Individual deafness genetic defect,If the same type of deafness deaf defect is a couple,The chances of their birth deaf are far higher than ordinary people.。
We should pay attention to the science of deafening,Be early screening early diagnosis early intervention,Especially in children just born even in the maiden, they have to do deafness.。
Why do you have normal pregnant women to detect deafness genes??
In the normal people in my country,Every100There is6A deafness mutation gene。These people are very high in fertility。80%The above deaf children are born by the normal parents of the hearing.。
