DMPK and dentatorubral-pallidoluysian atrophy: Maximum allele sizes sampled at these three loci were well below the range of pathogenic allele sizes: 32x at ATXN3 compared to allele sizes causative of SCA3 that range from 56x to 87x [112]; 26x at ATN1 compared to alleles causative of DRPLA that range from 49x to 88x [115]; 27x at DMPK compared to causative alleles of DM1 that range from 50x to 6500x [114].
