Description

Deaf sick tumor susceptibility gene plastosome 12SrDNA 1555A>G, 1494C>T mutant proportion detection kit
Technical field
The present invention relates to deaf sick tumor susceptibility gene plastosome 12SrDNA1555A > G, 1494C > T mutant proportion detection kit, belong to technical field of biological.
Background technology
The paathogenic factor research of the hearing and speech handicapped person being carried out in world wide shows, about 60-80% patient's the cause of disease is relevant with inherited genetic factors, and wherein the clinical study data of developed country show, hereditary hearing impairment accounts for 80% in deafness patient.Therefore in recent ten years, the pathogenesis of hereditary hearing impairment and the research of molecular epidemiology thereof become one of most important content of deaf sick research.Along with the Human Genome Project completes, the location of deaf ospc gene and clone have obtained huge progress, and the molecule genetics research of deaf disease and the data of molecular epidemiology make investigators progressively recognize that deaf sick susceptibility gene mutation safeguarding that hearing is healthy and finding the importance of hearing in abnormal.
The ototoxicity of medicine is an important factor that causes hearing loss before language, part and plastosome 12S rRNA gene 1555A > the G sudden change is relevant, and this sudden change can increase the susceptibility of cochlea to aminoglycoside drug.In the U.S., in the relevant hearing loss patient of ototoxic drug, 10% there is 12S rRNA gene 1555A the G sudden change, before U.S.'s language in the hearing loss patient, 1555A > G sudden change patient's sickness rate is about 1/20000-1/40000.In Spain, 12S rRNA gene 1555A > the G sudden change is relevant with the familial nonsyndromic hearing loss of 15-20%, the auditory dysesthesia that many old family members also can occur so suddenly change and cause even without the use aminoglycoside drug.And in China, the sickness rate of drug induced deafness has exceeded original imagination, in a series of article report, in the deafness patient that discovery is found in outpatient service, approximately 5% patient is due to 12S rRNA gene 1555A > G sudden change causes, and, in such specific group of school for deaf-mutes, up to 12% patient, be due to 12S rRNA gene 1555A G sudden change contact aminoglycoside drug causes deaf.In Chinese colony, also found 12S rRNA gene 1494C simultaneously > relation of T sudden change and drug induced deafness, at present at least had been found that three large familys are due to 1494C > T suddenlys change and causes.1555A > G sudden change and 1494C > often hearing is normal at birth for T sudden change person, is difficult to found in advance and predict by universal newborn hearing screening, but has the hidden danger that hearing loss occurs because of the use of ototoxic drug.Due to mitochondrial heterogeneous feature, the ratio difference of the mitochondrial mutations that different individualities shows.Large quantity research shows, 1555A > G and 1494C > there is certain dependency in the ratio height that occupies of T sudden change plastosome with the state of an illness, and the individuality that the plastosome that usually suddenlys change proportion is high shows severe deafness, and accounting is low shows slight deafness or normal.Even but the sudden change accounting is very low, still exists medicine to cause deaf danger.Therefore, need on the one hand the test kit that can tell mutant proportion for the relevant sudden change of the deaf disease of plastosome provides research means more easily, require on the other hand these reagent good Detection capability to be arranged to low mutant proportion sample.
Gene tester commonly used has at present: direct Sequencing (direct sequencing, DS), Ligase detection reaction (ligase detection reaction, LDR), restriction fragment length polymorphism analysis (restriction fragment length polymorphism, RFLP), dhplc analysis (denaturing high performance liquid chromotography, DHPLC), gene chip.All there is different defects in these methods, such as complex operation, result, are difficult for the problems such as interpretation, poor repeatability, false negative false positive be many.For the gene type of chromosome mutation, general fluorescence quantitative kit often needs same sample is carried out to the multitube detection, could obtain the somatotype information more than 2.Mutant proportion for Mitochondrial DNA detects, and mass spectroscopy can detect the sudden change of 5% left and right, and order-checking and gene chip can only reach 20% left and right for the mitochondrial selective power of sudden change, and indistinguishable goes out the sample of lower mutant proportion.
Above-mentioned plastosome 12SrDNA1555A is take in the present invention > G, 1494C > the T site is detected object, amplification and fluorescent quantitation by above-mentioned deaf susceptibility loci detect, contrast with the mutant proportion standard substance, can filter out the individuality that contains above-mentioned site mutation, determine the ratio of various sudden changes simultaneously.To the detection of deaf sick tumor susceptibility gene, especially significant to the examination of newborn infant's deaf gene; Utilize first the method for fluorescence quantitative PCR detection to realize 1494C > T, 1555A > target that the mutant proportion of G detects, greatly saved manpower and materials and time.The highly sensitive high specific detects simultaneously, provides the somatotype information of the relevant sudden change of karyomit(e), for plastosome 1555A > G and 1494C > selective power of T sudden change reached 0.1%.Stopped pipe detects and to have prevented the pollution of uncapping and detecting operation and producing, for clinical diagnosis and association area scientific research provide reliable method.
Summary of the invention
The object of the invention is to provide and a kind ofly can in 1 hour, detects deaf sick tumor susceptibility gene plastosome 12SrDNA1555A simultaneously > G, 1494C > the T sudden change, report the fluorescence detection reagent kit of the ratio of various sudden changes simultaneously.
