A 4-year-old angel-faced girl in Anhui suffers from a rare genetic disease. Why did she get such a disease?

On February 1 day, in Hefei, Anhui, it was reported that a four-year-old child? Lannini, with an angelic face. Suffering from it at birth? Neurodegenerative disease, cerebral hemisphere iron deposit type 6? Hereditary disease. It is understood that this disease is rare. Nini's mother said that Nini was only one year old when she was four years old. Because the genes of Nini's mother and Nini's father don't match, the child was defective the day before yesterday and his intelligence was affected. I can't speak now, and I can't take care of myself in all aspects of my life. The doctor said that I might face retrogression in the future, and Nini would become a vegetable. Nini's mother said that she started treatment when she was six months old. I am almost five years old now, and I have been treated for more than four years. The doctor said that Nini's illness could not be cured. I can only teach her more in peacetime and give her more training for autistic children. I hope she can take care of herself in the future.

I believe many netizens, like me, have heard about genetic incompatibility for the first time. From a medical point of view, it refers to incompatible genomes, usually called alleles. This probability is only one in ten thousand in normal couples. Alleles refer to the offspring who get the same gene from their parents, and a pair of alleles control a certain trait. The combination of some two alleles will make individuals unable to survive or have low viability, which may lead to infertility, recurrent abortion, tumor, different forms of diseases, rare diseases, weird personality and so on.

In our society, which advocates prenatal and postnatal care, the best way to exclude children with congenital diseases is to have premarital examination. But we don't force premarital examination. If both men and women have genetic diseases, we still suggest that women can do non-invasive DNA during pregnancy, check whether the child has problems, and do prenatal and postpartum examinations before pregnancy. ?

We hope that one day we can develop a medical solution that is genetically incompatible, so that Lannini can perceive the world and take care of itself like ordinary people. At present, the Lannini incident has attracted the attention of netizens. I believe that Lannini's parents will not give up the treatment of Lannini. We will continue to pay attention and let our kindness and love make Lannini feel happy and happy in the sunshine.
