“Characterization of repeat expansion disorders from long-read sequencing”

Short tandem repeats (STRs) are directly adjacent repetitions of specific nucleotide motifs in a genome. Here we first describe computational approaches to quantify repeats within STRs. In addition, long-read sequencing can also be used to characterize the haplotype structure of the region encompassing STRs. We demonstrate its use on a 10kb region in exon-1 of HTT, which causes Huntington's disease (HD). One SNP common to 30% of individuals with HD of European ancestry was identified for allele-specific CRISPR/Cas9 deletion of the expanded repeats in human HD cell lines. Our workflow can be applied to other repeat expansion diseases.
