single nucleotide polymorphism. A genetic change that is caused by substitution of a single nucleotide.
Defined regions of the genome where there are two or more nucleotide variations, each with 1% or greater prevalence in the population. SNPs can be used as genetic or physical markers.
DNA sequence variants (inherited single base changes) which occur frequently throughout the human genome (1 in every 3-500 bp) and are used as markers in whole genome linkage analysis.
ingle ucleotide olymorphisms. An SNP test is used to confirm your haplogroup.
Common, but minute, variations that occur in human DNA at a frequency of one every 1,000 bases. These variations can be used to track inheritance in families. SNP is pronounce "snip". (taken from www.genome.gov)
Single nucleotide polymorphism. A DNA sequence variation that involves a change in a single nucleotide
single nucleotide polymorphism. SNPs are used by anthropologists to identify deep ancestry ( haplogroups or clades). Haplogroups often can be estimated or predicted based on STRs but to be certain a SNP test is required. This information is not useful for contemporary genealogy Single Nucleotide Polymorphism (SNP) - (pronounced "snip"), a small genetic change or variation that occurs within a DNA sequence when a single nucleotide, such as an A, replaces one of the other three nucleotide letters: C, G, or T; occur so infrequently that they are used to define haplogroups ( From glossary in Trace Your Roots With DNA - by Smolenyak and Turner)
Single Nucleotide Polymorphism. Inter-individual variations in the genetic code at the level of one nucleotide.
Single Nucleotide Polymorphism. A change in the DNA that happens when a single nucleotide (A, T, G, or C) in the genome sequence is altered. A person has many SNPs that together create a unique DNA pattern for that individual.
Single nucleotide polymorphism. A change in which a single base in the DNA differs from the usual base at that position.
Single nucleotide polymorphism; a site on the DNA strand at which the base sequence differs among individuals (Pronounce "snip"). See also: SNP chips
SNP -- pronounced "snip" -- is short for "single nucleotide polymorphism".
Single Nucleotide Polymorphism. A single base difference found when comparing the same DNA sequence from two different individuals. More on SNPs reference: Weiss KM. In search of human variation. Genome Res 1998; 8(7): 691-7.
single nucleotide polymorphism – very small genetic variations between individuals
Single Nucleotide Polymorphism. A variation in a gene caused by the change of a single base in DNA.
acronym for single-nucleotide polymorphism
single nucleotide polymorphism. A variation of a gene that differs by one base pair. An example would be substituting an “A” where there is usually a “C” in the genetic code.
Single nucleotide polymorphism. Scattered single-base pair variations within the genetic code of the individuals of a population. SNPs determine ways that subpopulations within a species differ and provide information about variations of protein expression and structure of interest to p

(Single Nucleotide Polymorphism): A change or mutation in a single base pair in a DNA sequence. SNPs are relatively rare, and are unrelated to the short tandem repeat (STR) mutations found on the Y chromosome. SNPs are used to define haplogroups.
Variations in the sequence of DNA among individuals that are present in humans with a frequency of about once in every 1000 bases, and useful in assessing the patterns of inheritance in genetic linkage studies.
A single base pair variation at a particular genetic locus. SNPs are abundant in the genome and form part of the natural genetic variation. Can be detected using microarray technology and useful for genetic mapping and association studies.
Single nucleotide polymorphism. A change in a single "letter" of DNA "text", such as replacing a C with an A in one location. However, not every random change is categorized as SNP but only those which, compared to the average human genome, appear with a frequency of at least 1% in the population. Every individual carries numerous SNPs, some of which can result in disease. Target validation Basic step in drug development; test of the specific effect of a drug candidate on a target biomolecule, with the intention to create a therapeutic effect.
Single Nucleotide Polymorphism. Intraspecies variation at a given site in a nucleotide sequence.
Single Nucleotide Polymorphism. Most precise DNA marker technology, with excellent automation potential, but requires a great deal of additional genome characterization and technology optimization before it can be routinely applied to any plant species.
(Single Nucleotide Polymorphism) Point Mutation - Single base substitution variation - present in population at a frequency at or above 1
(pronounced: "snip") A SNP (single nucleotide polymorphism) is a single chemical unit (base pair) variation in a stretch of DNA. Human DNA is estimated to vary only 1 in every 1000 base pairs between any two people.
single nucleotide polymorphisms. A change in a single nucleotide (A, T, C, or G) in a gene sequence causing a change in expression of the gene in the individual's phenotype.

Single Nucleotide Polymorphism. A common single-base pair variation in a DNA sequence.
Single Nucleotide Polymorphism. The most common genetic differences among individuals resulting from minute, single-base changes in the genetic code.
Single nucleotide polymorphism, pronounced “snip.” A gene variation that consists of alteration in a single genetic “letter,” or base: for example, GGT instead of GCT. Such common, though minute, variations occur in human DNA at a frequency of one in every 1,000 bases.
Single nucleotide polymorphism. single-base variations in the genetic code between different individuals of the same species.
Single nucleotide polymorphism. Single nucleotide variations in the genome sequence.
Single nucleotide polymorphism. Individual differences at a single nucleotide of DNA. This genotypic difference can cause a phenotypic difference in hair colour, height or response to a drug, depending on the gene.
A SNP (pronounced "snip") is a place in the genetic code where DNA differs from one person to the next by a single letter. These slight genetic variations between human beings may predispose some people to disease and explain why some respond better to certain drugs.
Single nucleotide polymorphisms. Pronounced â€œsnipâ€. A variation in a single DNA nucleotide or code (recipe) for a protein. Most of the variation in people is due to SNPs There are millions of these in humans. However, only certain SNPs are functional, i.e., associated with a difference in molecular function significant enough to effect clinical measurements and risk of disease. Numbers are used to identify the chromosomal locations of SNPs and hetero - or homozygosity.
Single nucleotide polymorphism. The most common type of DNA sequence variation. An SNP is a change in a single base pair at a particular position along the DNA strand. When an SNP occurs, the gene's function may change, as seen in the development of bacterial resistance to antibiotics or of cancer in humans.
Inter-individual variations in the genetic code at the level of one nucleotide, a building block of DNA. These variations occur so seldom they are used as the basis for forming haplogroups.
SINGLE NUCLEOTIDE POLYMORPHISM. Variability among individuals of the DNA sequence at one specific base within a gene. Particular SNP sites within the coding regions of proteins are chosen for investigation because nucleotide changes (i.e. mutations) at these sites could lead to amino acid substitutions that will affect protein function. Each SNP is studied to determine if it is associated with a genetic disease.
