Benefits of Genetic Testing

It must be appreciated that genetic testing has dramatically improved lives and has potential benefits for both positive and negative tests results.

  • Genetic tests are employed to confirm diagnosis of a genetic condition and to help in the management of the disease..
  • Uncertainty often leads to stress and the genetic test results can provide a much-needed sense of relief. Genetic testing and counseling help people to make decisions about managing their health care. Testing negative for an abnormality helps to avoid unnecessary check ups. Testing positive for a mutation enables a person to look for preventive or treatment options.
  • Genetic testing helps to identify people who are more prone to develop a medical condition that may be preventable. For example, asymptomatic people with the BRCA gene mutation may opt to remove their breasts and ovaries as a prophylactic measure. Similarly, individuals with a family history of familial adenomatous polyposis have been saved by colonoscopy and removal of growths in the colon or by colonectomy. A smoker, with a cardiac family history, is cautioned well in advance to modify his lifestyle.
  • Certain genetic screening can also help people to take decisions about having children. Some tests allow families to prevent passing on these problems to the next generation, by not producing children with incurable and devastating diseases or anomalies.
  • Screening in new born children helps to identify a genetic abnormality early in life. This helps to start treatment as early as possible.

One of my relative's son has low biotinidise enzyme. He was born 2 weeks ago in USA and is using biotin 5MG tablets now. They are in USA and want to come to Chennai - in 3 months from now [2-June-2015]. They were told that a blood sample needs to be tested for biotin every 6 months to adjust the dosage of Biotin prescribed for the baby. Is Biotin tablets for infants available in Chennai? Is there medical centers/labs/doctors at Chennai who treats such biotin related gene disorder? Any early response is greatly appreciated. Thanks !

Hello Doctor, can you please suggest the best place in India for genetic counseling. My daughter who is now 5 1/5 years old had long segment hirschsprungs diseases at birth which was treated with pull through surgery. Both me and my husband are not aware of any family history of hirschsprungs in our family. Now I am planning for another kid but before that want to be sure of the underlying reason for my daughter's condition and the chances of recurrence in future pregnancies. Any advice on this will be very much appreciated. Thank you!

The best genetic counselor in India by popular consensus is Dr.Ashok Prasad who is a professor also holding a genetic counseling masters from Brandeis University. He works only on a charitable basis in Gorakhpur but am sure could be persuaded to advise you
