Severe combined immunodeficiency disease (SCID) is one of the most critical primary immunodeficiency diseases, and most of these children do not live one year old. However, the karyotype-targeted PGD technology and the pediatric cross-linking medical model of gynaecology and obstetrics have enabled a successful third-generation IVF that was successfully blocked by X-linked severe immunodeficiency disease. According to the investigation, there is no precedent in China. The Obstetrics and Gynecology Hospital affiliated to Fudan University revealed on the 30th that this lucky male baby weighs 3,700 grams and has good physical indicators. After examination by the Fudan University Pediatric Hospital, the child's immune function is normal. It is reported that four years ago, the child's mother Wu Ting (a pseudonym) had given birth to a baby boy in full term. A series of symptoms of lack of immunity appeared shortly after birth, and various infections continued. The baby was diagnosed with severe combined immunodeficiency (SCID) by the team of Wang Xiaochuan, clinical immunology department of the Pediatric Hospital affiliated to Fudan University, and found the causative gene, which is a defect in IL2RG gene. In the end, the child died unfortunately after 2 months of serious infection. Professor Wang Xiaochuan introduced that primary immunodeficiency disease (PID) is a kind of disease that seriously affects children's life and health, mainly due to abnormal congenital differentiation of immune organs, immune cells or immune molecules, resulting in humoral and/or cellular immunity. Defects, death, and disability. Severe combined immunodeficiency disease (SCID) is the most critical primary immunodeficiency disease. The child is usually ill for 1 to 2 months, and is resistant to infections such as bacteria, fungi, viruses, and mycobacteria, and there are repeated serious fatal infections. Most children do not have the opportunity to get timely diagnosis and stem cell transplantation. And died within 1 year old. Current genetic studies have shown that 50% to 60% of the above diseases are X-linked recessive inheritance, and there are cases of autosomal recessive inheritance and sporadic cases. "X-linked severe combined immunodeficiency disease" is a rare disease with an incidence of less than 1 in 100,000 in the normal population. After genetic testing, the disease-causing gene of the child was inherited from the mother, and Wu Ting carried the heterozygous mutation of the IL2RG gene on the X chromosome, while the male gene was normal.
