Sequencing system Roche GS Junior 454: Q20 read length of 400 bases (99% accuracy at 400 bases and higher for preceding bases)(Roche). Error rates usually originate in homopolymeric stretches. If such problems are encountered or if pathogenic sequence variants are found, we validate the NGS data with Sanger sequencing.
