A do-it-yourself home genetic testing could forecast the risk of developing macular degeneration, a principal reason for sightlessness, could egg on scores of individuals in taking crucial steps to help protect vision.
Saliva samples are forwarded for examination to asses an individual’s heritable risk of age-related macular degeneration (AMD), the widespread reason for loss of sight in the United Kingdom that has been observed to affect over a half million individuals.
Based on the outcome, the patient could then adopt modifications to his/her lifestyle and dietetic intake which have been proven to considerably lower the chances of developing macular degeneration.
Macular degeneration (AMD) or age-related macular degeneration is a condition linked to aging which eventually harms central vision that is vital for clear viewing of items and performing routine activities like read and drive. AMD is the result of macula (middle area of the retina) that conveys sharp, explicit imagery to the brain fails to function properly.
In spite of medicines, the condition has been observed to advance and half of those who suffer from this condition listed as having partial vision or sightless.
Regrettably, it has hardly any early signs, and by the time the condition is detected there is mostly long-standing harm to eyesight.
Despite the fact that nearly 70-80% of AMD cases could be tracked back to genetics, with kin members inheriting the condition, till lately there was no means of ascertaining who could be likely carriers of such genes.
But, this novel genetics test that has proven to have 100% accuracy in identifying genes that could raise risk for AMD, such an evaluation is now achievable.
The D.I.Y test costing near four hundred pounds comprises of a tiny test-tube wherein saliva sample is to be placed. The test-tube on sealing is then forwarded in a pre-paid covers for laboratory evaluation. The lab testing weighs up 6 genes and 8 heritable markers which have been associated with a heightened risk of developing AMD. The assessment of these genes offers a tailored analysis of heritable risk.
The person obtains a complete report in two weeks and in case considered to be at a risk of developing AMD, they would receive a call from their genetic analyst for a complimentary consulting session.
The test is particularly beneficial among those having relations with this condition. On discovering whether one has heritable high-risk genes then appropriate measures could be taken like weight reduction, smoke cessation and augmenting veggie and fruit intake in one’s dietetic intake – all aspects which could lower AMD risk considerably.
But, there are cases wherein despite having high-risk genes for AMD would not develop the condition during their lifetime. In such scenarios, genetic testing would lead to pointless worries.
However, despite those considered belonging to high-risk, still lifestyle modifications could not be adequate to avert sightlessness.
