CAG repeats thus causing the symptoms of HD to appear at an earlier stage (Walker , 220 . Before the discovery of the exact gene responsible for producing HD , the identification of carriers in an asymptomatic stage was done though linkage analysis based on the detection of a genetic marker for HD .6 Linkage analysis takes advantage of the spatial proximity of a genetic marker and the mutation by examining the pattern of DNA near the gene in both parent and fetus...
