Abstract
The interest in the functional aspects of the genome has increased eventually with the expansion of genomic databases. In this review, various genetic alterations within the genome, such as Single Nucleotide Polymorphisms (SNPs), disease-associated mutations, neutral polymorphisms, and small insertions or deletions (INDELs), have been identified and characterized. These polymorphisms, particularly SNPs, have become widely employed in genetic analyses, serving as valuable molecular markers. They are applied across diverse genetic studies, including the reconstruction of haplotypes. In addition to experimental methods for investigating specific genetic variants, there has been a significant surge in bioinformatics research over the past decade, aimed at the molecular consequences of these genetic alterations. Haplotypes, which represent various alleles of a gene, can be reconstructed not only for entire chromosomes but also for specific genes, utilizing the information derived from SNPs. The computational approach to SNP and haplotype discovery has gained prominence due to the continuous expansion of sequence data within public databases. This growth enables more precise identification of SNPs. This article aims to introduce easily accessible and practical online tools for researchers. In summary, SNP and haplotype identification tools are indispensable in bioinformatics for studying genetic variation, population genetics, disease associations, and personalized medicine. They provide valuable insights into the genetic underpinnings of various traits and diseases, helping advance our understanding of genetics and its applications in healthcare.
