Take molecular genetics and bioinformatics for example; these are perhaps two of the most exciting areas of biology and are beginning to have an impact on other areas of medical therapeutics such as cancer and diabetes, and provide a signpost to ‘personalised medicine’. Yet recent genome wide association (GWAS) studies of large samples, have demonstrated that in schizophrenia around 1000 or more genetic variants of low penetrance may be implicated in the heritability of schizophrenia. The crux of the schizophrenia enigma is that we are dealing with a complex family of disorders affecting the most complex of cognitive functions,.
