Embodiment 1

[0063] 1 Detection of ERBB4 mutation in a family with epilepsy

[0064] 1.1 Subjects: The proband of Tu's epilepsy family and its family members from Fuling area of ​​Chongqing, the genetic map of the family is as follows figure 1 As shown, the test objects include 2 epilepsy patients (member number 13 in the figure), and 1 normal family member (member number 2 in the figure); number 1 and 3: generalized tonic-clonic seizures; number 2: no disease. A detailed physical examination was performed on all family members No. 1-3, and blood samples were collected from each person after signing the informed consent.

[0065] 1.2 Sequencing:

[0066] The collected blood samples were sent to Beijing Mikino Gene Technology Co., Ltd. for sequencing for epilepsy gene mutation screening and verification, and the relationship between clinical phenotype and genotype was analyzed. The results are as follows:

[0067] Align the measured sequence with the normal ERBB4 standard sequence (https:...

Embodiment 2

[0073] This embodiment provides a kit for detecting the ERBB4 1972 site mutation, which includes: a primer for detecting whether the ERBB41972 site has a mutation A1972T, a forward primer: TTCACAAGCTTTGTTTAACGGAC, a reverse primer: TGTGGATAATGTCTTGTACAACTGC; and a PCR amplification reagent: 10×Buffer (containing 15mM Mg 2+ ), dNTP (2.5Mm), high-fidelity DNA polymerase pfu DNA polymerase (5U / μl) and ddH 2 O.

[0074] The method for detecting whether the mutation A>T occurs at the 1972nd position of ERBB4 by using the kit mainly includes the following steps:

[0075] (1) Extract sample DNA and use it as a template to perform PCR reaction using the above-mentioned PCR reaction kit.

[0076] (2) Detection of multiple PCR products: Electrophoresis was performed on the PCR amplification products with agarose gel to detect whether the PCR amplification was successful, and the size of the amplified fragment was 379 bp.

[0077] (3) The PCR product is directly sequenced, and the seq...

Abstract

The invention discloses a marker for assisting epilepsy diagnosis and a detection kit of the marker, and relates to the field of the epilepsy diagnosis. Research for detecting an ERBB4 gene of membersof an epilepsy family discovers that the ERBB4 gene of the members suffering from epilepsy in the family has mutant c.A1972T; the gene mutation results in variation of 658th amino acid of the corresponding ERBB4 gene protein from isoleucine (I) to phenylalanine (F), and the variation is missense mutation; nucleic acid molecules containing the mutant c.A1972T or protein containing mutant p.I658F can be used as a biomarker for the epilepsy diagnosis, and a quick and reliable detection auxiliary marker is provided for the epilepsy diagnosis in molecular level.

Description

technical field [0001] The present invention relates to the field of epilepsy diagnosis, in particular to a marker for assisting epilepsy diagnosis and a detection kit thereof. Background technique [0002] Epilepsy is a syndrome of chronic recurrent transient brain dysfunction. It is characterized by recurrent epileptic seizures caused by highly synchronized abnormal discharge of brain neurons. Epilepsy is one of the common diseases of the nervous system, second only to stroke in prevalence. The incidence of epilepsy is age-related. It is generally believed that the prevalence rate is the highest within 1 year of age, and gradually decreases after 1 to 10 years of age. The ratio of male to female patients with epilepsy in my country is (1.15-1.7):1. [0003] The etiology of epilepsy is extremely complex and can be divided into three categories, and there are many factors that affect the onset: [0004] 1. Idiopathic epilepsy [0005] Suspicious genetic predisposition ...
