Genotyping Genetic Pre-Disposition, and Heterogeneity

SNPs allow us to pinpoint the genes involved in traits and diseases such as asthma, hypertension, obesity, cancers, and diabetes. They will enable both the localization of genes and gene families as well as the development of personalized medicine. 

In 1999 several companies joined to form the SNP Consortium to create a database of several 100,000 SNP markers and make the available to researchers. Tlie companies and organizations of the SNP Consortium presently aie

Tlie problems of genetic testing ai c psychological or technical in nature. Issues related to insurance, employment discrimination and privacy have received much attention. Additional etliical concerns arise when no effective intervention is available and when prenatal testing is considered for diseases with late-onset or minimal effects.
