A major advantage of using disease-specific hiPSCs is that they allow the capture of the patient's genetic background and, together with the patient's medical history, will enable the researcher to uncover the disease genotypic-phenotypic relationship [ 6].
However, as yet, there is no consensus about which neoadjuvant regimen will be the most effective, either in general terms or for particular patients (as defined by disease or genotypic variation).
AUC: area under the curve; CD: Crohn's disease; GRR: genotypic relative risk; MAF: minor allele frequency; MZ: monozygotic; RAF: risk allele frequency; ROC: receiver operating characteristic; SNP: single nucleotide polymorphism; VE: variance explained.
When incorporating cases from the families into the analyses, the CCREL method (version 0.3) [75] was used to test SNP-disease allelic, genotypic and 2- and 3-SNP haplotypic associations.
The parameters used in the calculations were derived from our previous article [ 14]: high risk allele frequency and marker allele frequency 0.49, disease prevalence 0.10, genotypic relative risk Aa 3, genotypic relative risk AA 5, and D' 0.8.
Eye colour, body form, and disease resistance are genotypic variations.
See related editorial by Norton and Perez, http://breast-cancer-research.com/content/15/1/101 Breast cancer is a heterogeneous disease, with substantial genotypic and phenotypic diversity [ 1].
In sum, therefore, these phenotypic biomarkers do support prediction independent of the individual life stage and style in contrast to the prediction of disease susceptibility by genotypic biomarkers.
Additionally, sibling SNP data can be used to quantify an individual's disease propensity through genotypic inference, without that individual's actual sequence data.
Moreover, the real effect of a susceptibility gene and the impact of its discovery in the clinics can only be established using unselected and representative population samples, which allow for estimating prevalence of gene variants and relative genotypic disease risks.
As part of this process, discussions on the common clinical endpoint of brain neuropathology in Alzheimer's disease and on genotypic and phenotypic associations in Down syndrome are helpful.
