SNP genotyping

With a large genome-wide association study, researchers identified several significant associations in PDE4B, a gene with expression shifts in brain samples from stressed mice.

The assessment incorporates different ethnic backgrounds, but debate continues among researchers on the utility of polygenic risk scores for diabetes.

Although analyses for other drugs in the class have failed to confirm the influence of genotype, Dalcor is moving forward with its clinical trial, expecting some results by the end of this year.

The researchers found evidence of genetic continuity in Anatolia, even as the subsistence strategy changed from hunting and gathering to farming.

Investigators calculated that the new assay, which includes 67 SNPs, could offer a 50 percent improvement over previous methods if used in newborn screening.

The firm's lab subsidiary Phenogen will provide genotyping to study the impact on women's decisions to undergo prophylactic surgery.

The researchers generated a skull shape score and applied it to a European ancestry cohort to tease out introgressed Neanderthal DNA linked to head shape.

A GWAS meta-analysis involving hundreds of thousands of cases and controls led to new and known gallstone disease-associated variants at 28 loci.

A gene-environment analysis involving 10,346 twins suggests parents are more restrictive when feeding children who have a genetic propensity for weight gain.
