Personalized medicine involves the use of genetic methods by physicians for early diagnosis, prediction of the nature of the disease course and the choice of medicines and their doses based on personalized characteristics of the individual patient. Advances in the study of the human genome make it possible to reveal the interrelation between different varieties of alleles of human genes (polymorphism) and predisposition to certain diseases. Currently there are more than 10 million single-nucleotide polymorphisms in the human genome, but their biological role remains poorly understood. On the basis of a literature search of electronic full-text and abstract-only versions of articles’, which was conducted in the PUBMED, OMIM and GENE databases, collected was the information on genetic predisposition to systemic atherosclerosis. The review is dedicated to polymorphisms of the major genes that play a role in the pathophysiology of atherosclerosis of the lower extremities.

Detecting regions of the human genome that are, or have been, influenced by natural selection remains an important goal for geneticists. Many methods are used to infer selection, but there is a general reliance on an accurate understanding of how mutation and recombination events are distributed, and the well-known link between these processes and their evolutionary transience introduces uncertainty into inferences. Here, we present and apply two new, independent approaches; one based on single nucleotide polymorphisms (SNPs) that exploits geographical patterns in how humans lost variability as we colonized the world, the other based on the relationship between microsatellite repeat number and heterozygosity. We show that the two methods give concordant results. Of these, the SNP-based method is both widely applicable and detects selection over a well-defined time interval, the last 50 000 years. Analysis of all human genes by their Gene Ontology codes reveals how accelerated and decelerated loss of variability are both preferentially associated with immune genes. Applied to 168 immune genes used as the focus of a previous study, we show that members of the same gene family tend to yield similar indices of selection, even when located on different chromosomes. We hope our approach will provide a useful tool with which to infer where selection has acted to shape the human genome.

ABSTRACTSince the initial sequencing of the human genome, many projects are underway to understand the effects of genetic variation and phenotypic changes between individuals. Single nucleotide polymorphisms (SNPs) are an increasingly important tool for genetic and biomedical research. Synonymous Single Nucleotide Polymorphisms (sSNP) is an important source of human genome variability. It does not produce altered coding sequences therefore expected not to change the function of protein in which they occur. Examination of synonymous SNPs that change a rarely used codon into a frequently used one or vice versa may help in predicting their phenotypic effect on the individual carrying the change. Detail information of Human Synonymous Single-nucleotide-polymorphism may accelerate the research of personalized medicine since it has the crucial impact in the field of non-synonymous SNP.

AbstractBlastFrost is a highly efficient method for querying 100,000s of genome assemblies. It builds on Bifrost, a recently developed dynamic data structure for compacted and colored de Bruijn graphs from bacterial genomes. BlastFrost queries a Bifrost data structure for sequences of interest, and extracts local subgraphs, thereby enabling the efficient identification of the presence or absence of individual genes or single nucleotide sequence variants. Here we describe the algorithms and implementation of BlastFrost. We also present two exemplar practical applications. In the first, we determined the presence of the individual genes within the SPI-2 Salmonella pathogenicity island within a collection of 926 representative genomes in minutes. In the second application, we determined the existence of known single nucleotide polymorphisms associated with fluoroquinolone resistance in the genes gyrA, gyrB and parE among 190, 209 Salmonella genomes. BlastFrost is available for download at https://github.com/nluhmann/BlastFrost.

Studies on the interactions between single nucleotide polymorphisms (SNPs) and macronutrient consumption on weight loss are rare and heterogeneous. This review aimed to conduct a systematic literature search to investigate genotype–diet interactions on weight loss. Four databases were searched with keywords on genetics, nutrition, and weight loss (PROSPERO: CRD42019139571). Articles in languages other than English and trials investigating special groups (e.g., pregnant women, people with severe diseases) were excluded. In total, 20,542 articles were identified, and, after removal of duplicates and further screening steps, 27 articles were included. Eligible articles were based on eight trials with 91 SNPs in 63 genetic loci. All articles examined the interaction between genotype and macronutrients (carbohydrates, fat, protein) on the extent of weight loss. However, in most cases, the interaction results were not significant and represented single findings that lack replication. The publications most frequently analyzed genotype–fat intake interaction on weight loss. Since the majority of interactions were not significant and not replicated, a final evaluation of the genotype–diet interactions on weight loss was not possible. In conclusion, no evidence was found that genotype–diet interaction is a main determinant of obesity treatment success, but this needs to be addressed in future studies.
