The lure of genetic data can be compelling but misleading, for no list of tiny variants in one's genetic code can reliably predict one's future regarding cancer, heart attacks or diabetes, let alone I.Q., addiction or gullibility.
[If] you have a molecule useful in a biological system, then in other biological systems you will get that same molecule or tiny variants; methylated or o-methylated... Well now, they search for extraterrestrial life with radio telescopes waiting for a signal.
The real Proust industry is commanded by Tadié (professor of French at the Sorbonne), who has also edited the vast Pléiade edition that includes sketches, drafts and variants in tiny print.
It will be much harder to estimate the number of variants making up this combined effect as the Vg of each variant is probably tiny.
Each of the associated variants has a tiny statistical effect on risk at the population level and, collectively, the significant single nucleotide polymorphisms statistically account for only a few percent of the overall heritability of the disorder [ 18, 25, 26].
Open image in new window Fig. 5 Resolved tiny primary intimal tear of dissection variant IMH in a 68-year-old woman with hypertension who presented with unstable thoracoabdominal pain.
The major obstacles in treatment development are that gene disease associations reveal very little about the underlying biology and that any implicated gene variant explains only a tiny proportion of an individual's overall risk for an AUD.
Tiny neighborhood groceries carry dozens of variants.
From a pooled sample of many people's DNA, the scientists cloned tiny DNA snippets representing the common variants at each spot, creating a library of such snippets.
So, it is reasonable to expect that the number of common coronary disease variants will increase, although as each novel variant will be associated with increasingly tiny effects, it seems that the missing heritability gap will never be filled by common variants alone.
