Length of CAG Repeats in HTT Gene Expand with Age, Linked to Worse Clinical Outcomes, Study Finds
The length of CAG repeats within the huntingtin (HTT) gene tends to increase as people with Huntington’s disease get older and is directly correlated with poor clinical outcomes, a study has found. The study, “A genetic association study of glutamine-encoding DNA sequence structures, somatic CAG expansion, and…
