I have now used the PLINK software package also for analysing family data. Again it is an excellent program that allows many new views on old data. I could run >20 traits all together on ~1000 SNPs in just a few seconds. There are only a few tweaks that I have already emailed to the author Continue reading Tonk, Plonk and Plink
-moblog- In my view, epidemiology is not very flexible to adjust to new methods and new techniques. Following some discussion that I had today with STW about eQTLs (quantitative traits derived by RNA microarrays or metabolome profiles) and JMA about system biology, it is likely that we are facing huge changes. Phenotypes may no more called intermediary and we may soon forget old controversies of disease definition. We will instead use new system-terms like NonImm076Trig31Ste0098 or TLR9-096321-Auto5337. Yea, yea.
We find that the somatic epigenetic state of Avy is affected by in utero methyl donor supplementation only when the allele is paternally contributed. Exposure to methyl donor supplementation during midgestation shifts Avy phenotypes not only in the mice exposed as fetuses, but in their offspring. This finding indicates that methyl donors can change the epigenetic state of the Avy allele in the germ line, and that the altered state is retained through the epigenetic resetting that takes place in gametogenesis and embryogenesis. Thus a mother’s diet may have an enduring influence on succeeding generations.
