1 Improved Diagnosis of Inherited Retinal Dystrophies by High-Fidelity PCR of ORF15 followed by Next-Generation Sequencing  Jianli Li, Jia Tang, Yanming Feng, Mingchu Xu, Rui Chen, Xuan Zou, Ruifang Sui, Emmanuel Y. Chang, Richard A. Lewis, Victor W. Zhang, Jing Wang, Lee-Jun C. Wong  The Journal of Molecular Diagnostics  Volume 18, Issue 6, Pages (November 2016) DOI: /j.jmoldx Copyright © 2016 American Society for Investigative Pathology and the Association for Molecular Pathology Terms and Conditions

2 Figure 1 A: The coverage of the highly repetitive region of ORF15 is increased using PCR/next-generation sequencing (NGS) in three samples (solid lines) comparing with three samples that used capture-based NGS (dashed lines) or whole exome sequencing (gray lines). B: Two hemizygous in-frame benign variants, c.2541_2561del21 and c.2606_2620del15, are detected by PCR/NGS and confirmed by Sanger sequencing. C: A hemizygous in-frame benign variant, c.2820_2840dup21 (p.D943_E949dup), is detected by NGS (red box) and confirmed by Sanger sequencing. The original and duplicated sequences are underlined with blue and red lines in Sanger trace.

3 Figure 2 A and B: Two hemizygous frameshift pathogenic variants, c.2426_2427delAG (p.E809Kfs*25) and c.2899delG (p.E967Kfs*122), are detected in two young retinitis pigmentosa (RP) patients, P2 and P3, by next-generation sequencing (NGS) and confirmed by Sanger sequencing. C: A heterozygous 5-bp deletion c.2293_2297delGAGGG (p.E765Rfs*3) is detected in a female RP patient, P6, by NGS and confirmed by Sanger sequencing in forward (F) and reverse (R) directions.
