Prevalence and spectrum of single-gene CNVs in patients with intellectual disability

https://doi.org/10.25557/2073-7998.2021.10.44-46

Abstract

Single-gene CNVs were observed in 4.4% of patients with intellectual disabilities and developmental delay and were characterized by such criteria as type (deletion/duplication), localization, and origin. It has been shown that not all single-gene variants identified by aCGH can be confirmed by real-time PCR.
