Abstract

The genetic basis of congenital mental retardation includes chromosomal anomalies and single gene mutations. In addition to chromosome microarray analysis, next‑generation sequencing (NGS) and Sanger sequencing have additionally been applied to identify single gene mutations. However, no methods exist to identify the cause of an anomaly in one step. The present study applied an improved targeted NGS method to diagnose an 8‑year‑old Chinese Han female with mental retardation in one step. The microdeletion 17p11.2 was successfully detected by the improved targeted NGS and no single gene mutations were identified. The same microdeletion was verified using low coverage whole‑genome sequencing. Fertility guidance was also given to the patient's parents. In the present study, an improved targeted NGS method was applied to diagnose non‑syndromic mental retardation of unknown cause in one step. This improved method has the potential to be developed into a screening panel for the effective diagnosis of genetic abnormalities in non‑syndromic mental retardation and other congenital anomalies.
