Problems solved by technology

However, not all mutations in any of the aforementioned genes are associated with Marfan syndrome; the diagnosis of Marfan syndrome by detecting the few existing SNPs will inevitably lead to false negative test results

Abstract

The invention provides a mutant gene. The mutant gene is characterized in that the mutant gene is obtained through at least one mutation type of the following eight types comprising c. 4987T>G, c. 3617G>A, c. 5032T>G, c. 4087G>A, c. 4588C>T, c. 2861G>T, c. 718C>T and c. 4460A>G based on a human FBN1 gene. The invention further provides application of a related reagent used for detecting the mutation sites of the c. 4987T>G, the c. 3617G>A, the c. 5032T>G, the c. 4087G>A, the c. 4588C>T, the c. 2861G>T, c. 718C>T and / or the c. 4460A>G of the human FBN1 gene in preparation of a screening reagentfor the Marfan syndrome. The mutation of the sites of the c. 4987T>G, the c. 3617G>A, the c. 5032T>G, the c. 4087G>A, the c. 4588C>T, the c. 2861G>T, c. 718C>T and / or the c. 4460A>G of the human FBN1gene is applied to preparation of the auxiliary diagnostic kit for the Marfan syndrome, and the screening purpose can be achieved.

Description

technical field [0001] The present invention relates to the field of SNPs, in particular to SNPs related to Marfan syndrome. Background technique [0002] Marfan syndrome, also known as congenital mesodermal dysplasia, Marchesani syndrome, spider sign, elongated limbs, is characterized by peripheral connective tissue dystrophy, skeletal abnormalities, internal eye disease, and cardiovascular abnormalities , is a genetic disorder in which the basic defect of connective tissue is present. Marfan syndrome was first reported by Marfan (1896) in a 5-year-old girl with exceptionally slender and long limbs. By 1902, Achard called this sign spider fingers. Salle (1921) had dissected a baby with this syndrome and found a patent foramen ovale. By 1931, Weve confirmed that the syndrome was a dominant genetic disease and believed that it was caused by abnormal development of mesoderm tissue. [0003] There is no cure for Marfan syndrome, and only limited relief of specific symptoms ...
