糖尿病家系的分子遺傳學研究
[Abstract]:Three parts of the diabetes pedigree were studied: mitochondrial genome of 2 diabetic families inherited by matrilineal lineage, gene detection and functional analysis of 3 adolescent diabetic families with onset of disease in adults. Application of Genome scanning in Diabetes pedigree. Previous studies have shown that mitochondrial DNA is closely related to the development of type 2 diabetes. In order to reveal the correlation between mitochondrial DNA mutation and type 2 diabetes mellitus, we studied two maternal lineages of type 2 diabetes mellitus with similar extraneous rates, and sequenced the whole mitochondrial genome in order to reveal the relationship between mitochondrial DNA mutation and type 2 diabetes mellitus. The two families were from southwestern China. By sequencing the mitochondrial genome of the proband, we found that A and B belong to A4 and D4h1 haplotypes, respectively. Family B's mitochondrial gene ND5 has a private mutation, G13759A, which occurs in the first codon of the mitochondrial gene and can cause amino acid changes (alanine to threonine). But further evolutionary and developmental phylogenetic analysis suggests that the mutation has multiple origins and may be a polymorphic locus rather than a pathogenic gene mutation. No mutations in mitochondrial genes were found in these two type 2 diabetic families with similar maternal genetic background. In addition to mitochondrial genes, other maternal genetic mutations (nuclear genes or interactions between nuclear genes and mitochondrial genes) may play an important role in Chinese maternally inherited type 2 diabetes mellitus. Adult onset of adolescent diabetes (maturity-onset diabetes of the young, MODY) is an autosomal dominant single genetic disease type of diabetes mellitus, developed before the age of 25 and inherited for at least 3 generations). Clinical and MODY gene analysis were carried out in three MODY families in China. The MODY genes were identified as hepatic nuclear factor-4 偽 (HNF-4 偽), hepatic nuclear factor-1 偽 (HNF-1 偽), insulin promoter factor 1 (IPF-1), hepatic nuclear factor 1 尾 (HNF1 尾) and neural differentiation factor 1 (NEUROD1). One HNF4A mutation (p.T130I) and two HNF1A variants were found in these MODY families. Mutation (p.I27L and p.S487N). T130I induced a decrease in the expression of hepatocyte nuclear factor-4 偽. It is associated with both adolescent and adult diabetes. Our further function has confirmed that the p.T130I mutation of HNF4A, which can alter the expression of HNF4A. HNF1A p.S487N, is also one of the causes of diabetes in these patients. In this study, conservative analysis and functional prediction of p.T130I0I27L and p.S487N were carried out, suggesting that the variation of HNF4A and HNF1A in Chinese population may be one of the causes of diabetes mellitus in Chinese adults. The whole genome of 13 members of a diabetic family was scanned by TagSNP multipoint parameter linkage analysis and multipoint nonparametric analysis, and haplotype analysis was performed. It was found in one region that the LOD value of chromosome 20 was 30.8 cm and the LOD value of chromosome 16 was about 2, which might be linked inheritance. These regions have these genes associated with energy metabolism: LCB1, PLCB4, LAMP5,PAK7,SNAP25-AS1,SNAP25,MKKS,SLX4IP,JAG1. However, we sequenced these genes and found no significant mutation sites.
