Embodiment

[0040] The detection method of the present invention is used to detect the mutation sites of the above-mentioned known genes. Of course, the method can also be used to detect unknown mutations of the parkin gene, but the design of the primers will be different. The concrete steps of detection method of the present invention are as follows:

[0041] Step 1 DNA sample extraction

[0042] Specimen Collection and Processing

[0043] Take 10ml of cubital venous blood (sodium citrate anticoagulant) from the tested subjects, store it at 4°C, and use the following method to extract DNA within two weeks for future use.

[0044] DNA extraction

[0045] Use the second edition of "Molecular Cloning" to extract DNA from total blood. The specific steps are as follows:

[0046] 1) Add 10ml of cubital venous blood into a test tube containing 1.75ml of acid citrate dextrose solution B (ACD) and mix well;

[0047] 2) Place the test tube in a high-speed centrifuge at 3000 rpm, centrifuge f...

Abstract

The invention relates to the gene mutation relevant to the paralysis agitans and the detecting method, comprising: extracting DNA sample; designing primer; expanding with PCR; analyzing nucleic acid by means of dHPLC technology; testing the gene order of the sample which is dHPLC positive reaction to definite the genetype; carrying out beta-actin comparison for the sample of repeated extanding negative reaction to eliminate extron deletion mutation. The parkin gene mutation is in the codon promoter of the parkin gene, the second basic group in the exon1, ATG mutated to ACG; on the intersection point of thefifth introne and sixth extron in the exon6, AG mutated to AC; in the sixth extron, the 727th basic group, G mutated to A; in the exon9, the 1016th basic group, C mutated to T; in the position of ring finger intermediate region, in the Znf C6HC zinc region, GCG mutated to CGTC. By applying the gene mutation and the detection method, the detection for the mutation site of the parkin fene is high-effective and low-cost, and the diagnose to the potential PD patient can be made in an early stage.

Description

technical field [0001] The invention relates to a gene and a detection method thereof, in particular to a detection method of Parkin gene mutation and mutation site. Background technique [0002] The development of population aging makes senile diseases become an increasingly serious social problem. Statistics show that my country's elderly population over 60 years old has accounted for 10% of the national population (Beijing has exceeded 15%), and will reach 25% of the total population in 2030. Parkinson's disease (PD) is a progressive neurodegenerative disease closely related to aging. According to reports, the prevalence of PD in my country is more than 57-300 per 100,000 population, and the prevalence among people over 60 years old is more than 2%. It is conservatively estimated that there are one million PD patients in my country. Because PD seriously affects the patient's exercise and living ability, the disability rate is high, and the course of the disease can las...
