Genetic relationship was analyzed between type traits and longevity measures in dual-purpose cattle. Data from 91 486 Czech Fleckvieh cows first calved between 2003 and 2009 were used. Longevity was d...
Why might the finding of a new genetic association with inflammatory bowel disease be of potential value in disease control?
new genetic association inflammatory bowel disease potential value disease control
2018/11/20
Inflammatory bowel disease (IBD) has long been recognized as an exaggerated inflammatory response to common antigenic stimuli in the gut. Ulcerative colitis (UC) (1) and Crohn disease (CD) (2) are the...

Background: Many genetic variants show highly robust associations with body mass index (BMI). However, the mechanisms through which genetic susceptibility to obesity operates are not well understood. ...
Association of TCN2 rs1801198 c.776G>C polymorphism with markers of one-carbon metabolism and related diseases: a systematic review and meta-analysis of genetic association studies
cobalamin c.776G>C genetic association studies
2018/11/20
Background: Vitamin B-12 (cobalamin) deficiency may produce severe neurologic and hematologic manifestations. Approximately 20–25% of circulating cobalamin binds to transcobalamin 2 (TCN2), which is r...
Differences in genetic and environmental variation in adult BMI by sex, age, time period, and region: an individual-based pooled analysis of 40 twin cohorts
BMI adults genetics twins international comparisons
2018/11/15
Background: Genes and the environment contribute to variation in adult body mass index [BMI (in kg/m2)], but factors modifying these variance components are poorly understood.
