Over the past few years, inroads into understanding genetic predisposition by glycemic and nonglycemic factors have been achieved through genome-wide analyses.
The GLACIER (Genetics of lobular carcinoma in situ in Europe) study, MREC 06/Q1702/64, has ascertained patients from throughout the UK with the aim of understanding genetic predisposition to LCIS and/or ILC.
Considering the complexity of genetic and environmental contribution to alcohol dependence, this finding is a step towards understanding the genetic predisposition to alcohol-related phenotypes.
Therefore, identification of such variation is a major step toward understanding the differential predisposition to common diseases and variation in drug responses among individuals and ethnic populations.
Understanding the genetic predisposition to COPD is essential to develop personalized treatment regimens (Shapiro, 2011).
Finally, in Section 5, we will list some current challenges and possibilities as future directions toward improved understanding of individual predisposition to genetically complex diseases such as cancers.
Analysis of the genes involved and their human homologues may contribute to the understanding of individual predisposition to a high or low anti-tumor activity of lymphocytes and thus improve the decisions about personalized selection of appropriate therapies.
The discovery of the BRCA1 and BRCA2 genes, and of how mutations in these genes lead to the onset of breast and ovarian cancers has provided new insights into the molecular mechanisms that lead to tumourigenesis and have improved our understanding of cancer predisposition [ 1, 2, 3].
A major limitation to current progress in understanding the genetic predispositions to PTB is that only a limited number of genetic epidemiologic studies are available representing various ethnic/racial groups globally [ 49].
The heritability of RA was estimated from twin's studies between 40 and 77%.[2] Recently, significant progress has been made in our understanding of the genetic predisposition to RA, thanks to the implementation of genome-wide association (GWA) studies and intensive international collaboration.
