AR and Dentatorubral pallidoluysian atrophy: Apart from HTT, we searched the PolyASite 2.0 database [61] for information concerning alternative polyadenylation sites in eight other mRNAs: AR, ATN1, ATXN1, ATXN2, ATXN3, CACNA1A, ATXN7, and TBP, whose genes contain mutations responsible for spinal and bulbar muscular atrophy (SBMA), dentatorubral-pallidoluysian atrophy (DRPLA), and spinocerebellar ataxia types 1, 2, 3, 6, 7, and 17 (SCA1, SCA2, SCA3, SCA6, SCA7, and SCA17, respectively).
