These pages summarise hgvs-nomenclature: the recommendations for the description of sequence variants hgvs-nomenclature is used to report and exchange information regarding variants found in dna, rna and protein sequences and serves as an international standard.
Differences in the genetic sequence among individuals, genetic variation, can explain some of the physiological differences between people that may lead to an increased or decreased risk for disease while single genetic differences account for some diseases, common diseases are generally affected.

Genetic variation is the result of mutation, gene flow between populations and sexual reproduction in asexually reproducing organisms, some genetic variation may still result from random mutation mutations, or changes to the coding patterns of dna, lend to genetic variation when they are heritable.

Human variation there are many different types of human variation that are influenced by a population's geographic location, including skin color, height, and body proportions. Brain structure and neurological development figure prominently in some of the descriptions of neurodiversity on the internet: neurodiversity is the idea that variation in brain development and function should be appreciated and accepted as any other form of physical variation and: neurodiversity is defined as the whole of human. Members of the society have published a number of papers in relation to human genome variation and in particular mutation databases the society maintains a substantial collection of links to mutation databases and has made recommendations for nomenclature of variations, and content of mutation databases.

Human variation is commonly misunderstood in the context of racial classification a common perception of race is that human beings can naturally be divided into a small number of distinct races, that these races have certain inherent strengths and weaknesses, particularly in terms of intelligence, morality, and character, and that racial. Jonathan pritchard works to understand the nature of human genetic variation by combining methods from evolutionary biology and statistics he hopes to determine which of the vast number of individual differences in the human genome contribute to diseases and disease susceptibility.
