Gene Therapy to “fix” Genetic disorders!
"We used to think that our fate was in our stars, but now we know that, in large measure, our fate is in our genes, "quotes James Watson. This fate and our future is locked in our genes, and Gene therapy is unlocking these doors. Many physicians are predicting that in twenty years gene therapy may change the practice of medicine from a treatment-based to a prevention-based practice.
About Gene Therapy
Gene therapy is a novel therapeutic branch of modern medicine. Its emergence is a direct consequence of the revolution heralded by the introduction of recombinant DNA methodology in the 1970s. Gene therapy is still highly experimental, but has the potential to become an important treatment regimen. Basically, it allows the transfer of genetic information into patient tissues and organs in order to eliminate or restore the normal functions of the diseased genes.
Genetic disorders affect millions of people world-wide. Scientists have currently identified more than 4000 different genetic disorders. These are the harmful effects on an individual caused by inherited genetic diseases or mutations. Usually genetic disorders are recessive, so they are only expressed in a small percentage of the population, but a much larger percentage are carriers. When expressed in the homozygous recessive individual, they often code for the wrong protein or amino acid sequence. Gene therapy aims to get rid of these genetic conditions at their source.
Gene Therapy: Mending Genetic disorders
Gene therapy has made important medical advances in less than two decades. Within this short time span, it has moved from the conceptual stage to technology development and laboratory research to clinical translational trials for a variety of deadly diseases. During this period molecular genetic technologies have been spectacularly successful in identifying and characterizing novel disease genes, and in devising novel diagnostic tests for inherited disorders. Current and possible candidates for gene therapy in the field of genetic disorders include Severe Combined Immune Deficiency (SCID), Adenosine deaminase (ADA) deficiency and Duchenne muscular dystrophy (DMD) etc.
Gene therapy is likely to be most successful with diseases caused by single gene defects which is due to the absence of complex interplay between different genetic loci and/or environmental factors. However, some genetic disorders may not be so easy to treat as others and within the single gene disorder category differing pathogeneses means that certain single gene disorders will be more amenable to gene therapy approaches than others. However, low efficiency of gene transfer & expression and low longevity of gene expression are the acting limitations in this field. Inspite of this, there is much optimism and confidence in the potential of Gene therapy to develop an effective treatment for genetic disorders in the near future.
Gene Therapy: The Market Scenario
Many companies are investing in and researching on this field using gene therapy due to its promising effects. Large Pharmaceutical and Biotech giants, such as GlaxoSmithKline, Sanofi, and Bluebird Bio etc., are operating in the field of Genetic disorders in the gene therapy domain. A growing number of partnership between companies in drug development for example between Oxford BioMedica and Sanofi etc., are driving the new gene therapy research. The collective pipeline of industry is brimming with 300+ therapies of which genetic disorders collectively accounts for 11 % of gene therapies in pipeline. The global market opportunities for gene therapy have risen drastically and continue to be of great interest for many companies globally.
