Embodiment 1

[0030] A Parkinson's disease-causing gene, which comprises a nucleotide sequence of gene mutation (SEQ ID NO.33):

[0047] Example 2: A detection kit for Parkinson's disease-causing genes.

[0048] The specific components and contents of the detection kits for the aforementioned PD pathogenic genes are listed in Table 2.

Embodiment 3

[0051] Embodiment 3: Application of a detection kit of Embodiment 2 in the detection of Parkinson's disease-causing genes.

[0052] Take normal subjects (Ⅲ:6) and patients (Ⅲ:4) as subjects respectively, and perform the following operations:

[0053] 1. Genomic DNA extraction: 10ml of peripheral venous blood samples were collected from two subjects and passed through EDTA-K 2 For anticoagulation, the genomic DNA was extracted by the conventional phenol-chloroform method, and the DNA concentration and OD value were measured by a spectrophotometer, and then diluted to 100 ng / μl for later use.

[0054] 2. PCR amplification: use the detection kit designed in Example 2 to amplify the genomic DNA extracted in step 1 to obtain PCR amplification products. The components of the PCR reaction system (25 μl) are: 1 μl of DNA template (ie, the genomic DNA extracted in step 1); 2.5 μl of 10×PCR Buffer; 2.0 μl of 25 mM MgCl 2 10mM dNTP Mix of 0.32 μl; Forward primer (10 μmol / L) of 1.0 μl e...

Abstract

The invention discloses a Parkinson disease pathogenic gene and a detection kit. The Parkinson disease pathogenic gene is a gene which changes G gene into A gene at a 446th basic group of a GALNT2 gene coding region. The detection kit comprises a primer, wherein the primer is a primer designed according to all exons of a GALNT2 gene and an exon-intron junction region sequence; the primer is used for carrying out PCR (Polymerase Chain Reaction) amplification; a product obtained by the PCR amplification comprises the GALNT2 gene exon and a nucleotide sequence of an exon-intron junction region. The detection kit provided by the invention combines the PCR amplification and Sanger sequencing; the mutation of the PD pathogenic gene GALNT2 gene is detected; the detection kit is applied to clinical gene diagnosis and has the advantages that the detection is convenient and rapid, the accuracy reaches 100 percent and the like.

Description

technical field [0001] The invention relates to the technical field of gene detection, in particular to a Parkinson's disease-causing gene and a detection kit. Background technique [0002] Parkinson's disease (PD; MIM 168600), also known as Parkinson's disease, is a common motor system disorder and the second most common progressive neurodegenerative disease after Alzheimer's disease. Epidemiological data show that the prevalence rate has a certain relationship with age. The prevalence rate of people over 65 years old is about 1%, and the prevalence rate of people over 85 years old increases to about 4% to 5%. The average age of onset of PD is 70 years old, the standardized incidence rate of PD is estimated to be 8-18 / 100,000 / year, and the lifetime risk of disease is about 1.5%. In addition, gender may also affect the incidence of PD, and several prospective studies have found that the incidence rate of men is higher than that of women. The typical symptoms of PD motor sy...
