Genetic Testing

Dear Grandma,

I hope you are doing fine. Based on your request I have conducted the relevant research to make things apparent and meaningful to you. This will add great value to your knowledge and will help you towards reaching a decision. A sequence coming from the DNA tells our body how to produce proteins. The proteins which are being coded by our DNA are the responsible for the functions of our entire body. The diseases from which we suffer generally occur from our DNA not sending the right instructions to our body. This exposes a person to problems related to health.

Reading DNA would be very useful, as it will help us in finding people with certain DNA sequence which are susceptible to diseases (NDIC, 2012). Due to the sequencing of genes and if there is a disease sequence linked present, it is bound to happen that the person will be exposed to greater healthcare risk. One great way to identify diseases is to test the DNA of a larger population which is having health problems and then apply the sample to large number of people to find the DNA sequences that exist as a commonality. This will help greatly in making potential guesses about that particular disease.

Certain forms of heritable disorders such as particular cancer forms can be measured through genetic test kits. This disease occurs due to inherited genetic condition present is some people, which is transferred to other mutation in different people. These recessive gene disorders offer a sound advantage in specific environments where only a specific copy of gene is present (MedlinePlus, 2012).

Huntington's disease widely referred to an s a genetic disorder which triggers psychiatric problems in human beings and also affects person muscle coordination. When people reach their middle age this becomes more apparent. Huntington's test is based on questions being asked from an individual, psychiatric examination and family medical history. The neurological examination will ask question related to the psychiatric evaluation of the individual. The test will consider a person's well being and emotional state and will specifically cater to the reflexes and psychological wellbeing of the individual.

Complete feedback and evaluation is considered at all the stages which makes test more accurate. It takes comprehensive account of an individual, including his previous track record and family information. Brain imaging test such as MRI provides accurate ...
