It is expected that the sequencing of human genome and the genomes of other organisms will dramatically change our understanding and perceptions of biology and medicine. Some of the benefits of human genome project are given.
Understanding of polygenic disorders
The biochemistry and genetics of many single gene disorders have been elucidated E.g. sickle-cell anemia, cystic fibrosis, and retinoblastoma. A majority of the common diseases in humans, however, are polygenic in nature e.g. cancer, hypertension, diabetes. At present, we have very little knowledge about the causes of these diseases. The information on the genome sequence will certainly help to unravel the mysteries surrounding polygenic diseases.
Improvements in gene therapy
At present, human gene therapy is in its infancy for various reasons. Genome sequence knowledge will certainly help for more effective treatment of genetic diseases by gene therapy.
Improved diagnosis of diseases
In the near future, probes for many genetic diseases will be available for specific identification and appropriate treatment.
Development of pharmacogenomics
The medicines may be tailored to treat the individual patients. This will become possible considering the variations in enzymes and other proteins involved in medicines action, and the metabolism of the individuals.
Genetics basis of psychiatric disorders
By studying the genes involved in behaioural patterns, the causation of psychiatric diseases can be understood. This will for the better treatment of these disorders.
Understanding of complex social trait
With the genome sequence now in hand, the complex social traits can be better understood. For instance, recently genes controlling speech have been identified.
Development of biotechnology
The data on the human genome sequence will spur the development of biotechnology in various spheres.
