The focus of the conference was connecting how epigenetics (cellular and physiological phenotypic trait variations that are caused by external or environmental factors that switch genes on and off and affect how cells read genes instead of being caused by changes in the DNA sequence — in other words nutrition and lifestyle choices) impact whether or not an individual actually develops a specific health issue even though they have a SNP mutation.

Not exact matches

Their preliminary analysis revealed several mutations known as single nucleotide polymorphisms (SNPs) in the ALR gene, many of which haven't been identified before.

Instead they search specific regions of the genome for a type of mutation known as a single nucleotide polymorphism, or SNP (pronounced «snip»).

Conventional analyses look for individual mutations called SNPs — single - nucleotide polymorphisms.

Results from a statistical analysis shows a cluster of SNPs — single nucleotide polymorphisms — in one section of a single gene, indicating the location of a mutation likely linked to autism.

From beetles collected at 27 sites in Alberta and British Columbia, they looked for any patterns amongst their catalog of 1536 mutations (single - nucleotide polymorphisms, or SNPs).

Instead, the project can start out by testing participants» DNA for so - called single nucleodtide polymorphism (SNPs), common mutations scattered along the genome that can point to disease risk genes.

Polymorphisms observed in the consensus sequences of all individuals were cross-referenced with the MITOMAP database (http://www.mitomap.org/MITOMAP) of reported disease - associated mutations to determine whether any individuals harbored disease - causing mtDNA SNPs.

The presence of these SNPs in the ancient horses implies that selection for these traits did not occur on de novo mutations but on existing variation, which was either contributed to the domesticated stock by the ancient population through admixture or was cosegregating in both the ancestors of the ancient horses and the ancestors of the domesticated horses after their split.

The researchers zeroed in on a single - nucleotide polymorphism (SNP) that appeared to be the causal mutation, typically consisting of an adenine nucleotide but appearing as a guanine nucleotide in roughly a third of the population, located in a region of noncoding DNA that falls within the PHACTR1 gene.

Out of a total of five positively selected SNPs, four represented nonsense mutations resulting in stop codons, three of these in a single ApiAP2 transcription factor gene, and one in SRPK1.

It should be noted that the sensitivity for calling SNPs represents an upper bound for calling somatic mutations, since the latter often display mutant allele fractions less than 50 %.

This report describes the first COLQ mutation in canine CMS and demonstrates the utility of SNP profiles from nuclear family members for the identification of private mutations.

Whole genome association analysis studies that utilize single nucleotide polymorphism (SNP) markers have been used to identify the molecular causes of various traits and conditions including genetic mutations within breeds that cause coat color variations [15], hairlessness [25] and defects in spinal development [26].
