Increasingly, mutations in genes causing Mendelian disease will be supported by individual and small families only; however, exome sequencing studies have thus far focused on syndromic phenotypes characterized by low locus heterogeneity.
All these LD studies were performed using very informative microsatellite loci, but at a relatively low locus density.
Fertile T0 transgenic plants, which exhibited either normal or aberrant phenotypes, and further contained a low locus number of the transgene (one to two), were selected to grow on to the T1 and T2 generations.
After an initial round of mapping, loci were excluded from subsequent maps if they had a high frequency of suspect pairwise linkages, recombination fractions >0.60 and mapping LOD >1.5, high nearest neighbor fit values and low locus mean genotype probabilities, or if they had prominent order conflicts with the BC1/QTL-BASE2 reference map.
Furthermore, the risk of inadequate medication is rather high because of financial constraints (e.g. long-term treatment for diabetes is not affordable) or low locus of control and health knowledge (e.g. cost-free DOTS-therapy for tuberculosis is discontinued or medication is intermittent).
The close genetic distance between the two haplotype genomes might also explain the fact that WF1680 also had the second highest segregation distortion ratio for tested markers and the lowest locus density, both of which would cause unstable locus order.
This indicates that the Bxb1 expression T-DNA in these lines was at a single locus or a low number loci within the genome and that expression was sufficient to facilitate recombination, allowing segregation by self-pollination.
These results suggest that the major fraction of ChIP-seq DNA fragments maps to moderate and low avidity loci specific TFBSs and to background non-specific DNA loci.
Also for low risk loci, associations with breast tumor subtypes have been described [ 33, 34].
However, in both regional samples, high and low MAF loci were equally common.
