Prenatal diagnosis and genetic counseling of a de novo 10q11.22q11.23 duplication associated with a normal development at 12 months of age.
BACKGROUND Copy number variants are an important source of genomic variations, ranging from pathogenic to benign. The 10q11.22q11.23 region contains complex low-copy repeats that predispose to recurrent deletions and duplications via nonallelic homologous recombination. While some reports associate duplications of this...
