Description
Related application
It is on November 4th, 2015 applying date that the application, which is, and entitled " one kind is based in sequencing technologies detection β-ground of future generation
The division of the Chinese patent application 201510740909.5 of the multiple PCR primer and method of extra large anaemia mutation and application ".
Technical field
The invention belongs to biology field, be related to primer, more particularly to a kind of multiple PCR primer, a kind of kit,
The purposes and a kind of method of detection HBB gene sequence of multiple PCR primer and kit.
Background technology
β-thalassemia is a kind of because beta-globin gene (HBB) is mutated the list for causing peptide chain imbalance of expression and producing
Gene genetic blood disease, more caused by beta-globin point mutation.β-thalassemia is most common heredity in the world
One of, the whole world there are about people more than 100,000,000 and carry β-thalassemia gene according to statistics.β-thalassemia is also south China each province
One of most common, hereditary disease that harm is maximum, the β-thalassemia carrying rate in China part province is shown in Table 1.Thalassemia
Gene is mainly point mutation, and β-thalassemia gene covers 46 kinds of point mutation in southern china crowd.
The poor Population carriage in the southern china β of table 1 ground
| Area | β ground poor carrying rate (%) |
| Guangzhou | 2.54 |
| Guangxi | 6.78 |
| Sichuan | 2.18 |
| Guizhou | 4.72 |
| Taiwan | 1.10 |
| Hong Kong | 3.41 |
The gene diagnosis method of β-thalassemia mainly has：Sanger PCR sequencing PCRs, RFLP
(RFLP), reverse dot blot hybridization (RDB), ApoE gene (ARMS-PCR).The operation of Sanger sequence measurements is cumbersome,
Its application in clinical diagnosis is significantly limit, the detection flux of sequencing is also limited, and testing result is needed artificial
Analysis, analysis takes time and effort.RFLP is that method simplicity is with low cost by recognizing that specific sequence site carries out endonuclease reaction,
But its limitation is that the limited mutation for producing restriction enzyme site can only be detected, due to incomplete or partially digested reaction
Also result in false positive or false negative result.The result of reverse dot blot hybridization technology is with the naked eye interpretation, and fault rate is high, often results in
A sample is repeatedly detected.ARMS-PCR need to be needed excellent for the corresponding primer of each mutation design per pair of primers amplification condition
Change, when need to detect various mutations simultaneously if it is cumbersome, and false positive or false negative result occurs.
Market and social detection demand based on thalassemia dcc gene, and thalassemia dcc gene at present
The backwardness of present situation is detected, thalassemia gene mutation site detection kit gesture is developed must using high throughput sequencing technologies
OK.
