For a given number of informative meiosis, the higher the LOD score, the closer the distance between two markers, which means there is a high probability that the two markers are located in the same linkage group.
He also matched with people on his 12 and 25 Y Chromosome DNA markers, which meant that common ancestors related them from hundreds or even thousands of years ago.
However, this is hindered due to lack reliable diagnostic and predictive markers which mean that the majority of patients succumb to their condition within a few months.
Specific, pre-defined outcome measures are generally seen as the traditional marker of quality, which means that research questions that focus on processes rather than on 'outcomes' may be regarded as problematic.
GWA was first proposed in 1996 (Risch & Merikangas, 1996), but because microarrays were not yet commercially available, the only attempts to conduct GWA involved painstaking and expensive genotyping of each DNA marker individually, which meant that only a few thousand markers were genotyped (e.g., Plomin et al., 2001).
What needs to be revised in light of their cases, he says, is the definition of sleep.Dr Mahowald suspects that sleep can occur in the absence of the markers that currently define it, which means those markers are insufficient.
"One guy today, I said something about a marker and he said, 'A marker starts with mmm, mmm,' which means he's so close, he's going to get it tomorrow," she said excitedly.
Because of the assumed genetic influences, endophenotypic candidate markers must show heritability, which means that they should be observable (at least to some extent) even in unaffected relatives of schizophrenic patients.
HER2 overexpression is a good predictive marker of HER2 targeted therapy, which means that HER2 therapy will be very effective in reducing the size of HER2 positive breast cancers.
