遗传咨询者染色体多态性与临床效应的研究
[Abstract]:Objective to study the relationship between chromosome polymorphism and clinical effects in genetic counselors. Methods 1500 cases of genetic counseling were used to culture and prepare peripheral blood chromosomes by routine methods. G and C banding methods were used for karyotype analysis. According to the specific situation of the counselor, the microdeletion detection in AZF area was carried out. The relationship between chromosome polymorphism and clinical effect was observed and analyzed. Results chromosome polymorphism was detected in 110 cases, including 32 cases of interarm inversion of chromosome 9. There were 35 cases of small Y, 8 cases of large Y, 30 cases of short arm growth, 5 cases of secondary constriction on chromosome 1 and 9, and 5 cases of chromosome 16 in G group. Conclusion there is a corresponding relationship between chromosome polymorphism and clinical effects, which can lead to infertility, abortion and reproductive abnormalities such as stillbirth. Genetic counseling before pregnancy is of great significance to eugeny and fertility. [WT5 "HZ] conclusion [WT5" BZ] [WT5 "BZ]
