Single nucleotide polymorphisms (SNPs – pronounced “snips”) occur normally throughout a person’s DNA. They are the most common type of genetic variation found in people. Each SNP represents a difference in a single DNA building block, known as a nucleotide. Nucleotides form the basic structural unit of nucleic acids such as DNA.
SNP Genotyping: What It Can Reveal
Genotyping is the method and technology used to detect minute genetic differences that can lead to major changes in phenotype; these include both unique physical differences, and pathological changes that indicate underlying disease. SNP genotyping is the measurement of genetic variations of SNPs using technology. This is the type of genetic method used by the experts at Geneway.
There are roughly 4 to 5 million SNPs in a person's genome. When SNPs occur within a gene or in a regulatory region near a gene, they may play a more direct role in disease by affecting the gene’s function. SNP genotyping can indicate traits such as specific responses to certain medications, optimal diet for the individuals’ genetic profile, the likelihood of developing certain diseases, and much more. Some diseases, such as sickle cell disease and cystic fibrosis, stem from a single mutation. The severity of illness and the way the body responds to treatments are also manifestations of genetic variations.
SNP Genotyping from Geneway
Geneway offers a number of tests for different factors related to genes. Their SNP genotyping methods include tests such as:
Genewell: testing for an increased risk for certain (lifestyle) diseases
Genediet: testing for your genetic predisposition to being overweight, as well as your feeding behaviours, natural appetite control, the fat burning process, and more.
Generenew: testing for genetic factors for a young and healthy appearance, allowing you to understand your genetic profile in relation to your skin and appearance as well as anti-ageing within on cellular level to potentially increase longevity and quality of life as you grow older.
