In addition, we confirmed several genes containing CAG repeats associated with polyglutamine-associated diseases27,28, such as Ataxin1 (ATXN1), ATN1, Ataxin1 (ATXN7), calcium voltage-gated channel subunit alpha1 A (CACNA1A), TATA-box binding protein (TBP), and on-target gene, HTT in both human HD and human control fibroblasts. Here, ATXN7 is linked to Huntington disease.
