Huntington's Disease

I have Homozygous on the HTT genes;
rs362272 - AA
rs362273 - GG
rs362331 - CC
rs363092 - AA
rs6855981 - AA

How can you tell if there is a chance you can develop the disease? I have a lot of symptom and my grandfather on my moms side died early of many of the issues listed as being caused by the disease. He died in 1987 so long before there was ever genetic testing to find out what was wrong with him.

None of these variants will cause Huntington’s. The HTT gene contains a region where the letters the letters CAG are repeated multiple times. This is called a trinucleotide repeat. Most people will have between 10 and 35 repeats. People who develop Huntington’s have 36 or more repeats. A different type of DNA test is needed to test for this condition.
