PCR-free HiSeqX whole genome sequence data on 120 samples with triplet repeat expansions (premutation and full expansions)

Whole genome sequence (WGS) data was generated on 120 Coriell samples with the following validated repeat expansions: Fragile X Syndrome, Huntington disease, Friedreich’s ataxia, Amyotrophic Lateral Sclerosis, Myotonic Dystrophy, Spinocerebellar Ataxia 1/3 and Dentatorubral-Pallidoluysian Atrophy. These samples were sequenced using 2x150bp reads on an Illumina HiSeqX sequencer and the repeat expansions were called using ExpansionHunter to demonstrate the ability to call large repeats from high throughput, PCR-free WGS data.
