Targeted-capture sequencing was performed using a Roche NimbleGen custom 385K capture array. Paired-end sequencing libraries were generated after capture and sequenced on an Illumina sequencer. Whole-exome sequencing libraries were prepared using the Sure-Select Human All Exon v2 kit (Agilent) and sequenced on an Illumina sequencer. Whole-genome sequencing was performed by Complete Genomics. Targeted-capture and whole-exome data were analyzed using GATK (Van der Auwera et al. 2013 (link)). Whole-genome sequencing data were analyzed using Complete Genomics software. Variants were annotated with ANNOVAR (Wang et al. 2010 (link)) and filtered if their allele frequency was ≥1% in any of the following public variant databases: ExAC (Lek et al. 2016 (link)), 1000 Genomes Project (The 1000 Genomes Project Consortium 2015 (link)), NHLBI Exome Sequencing Project (Tennessen et al. 2012 (link)), and Complete Genomics 69 control genomes (Drmanac et al. 2010 (link)). See Supplemental Methods for further details.
