Xq25 microduplication involving exclusively STAG2 is a new distinctive cohesinopathy including mild to moderate intellectual disability, speech delay and facial dysmorphism. Seizures seem to be scarce, but detailed seizure type descriptions are missing. We report the case of an 8-year-old boy with mild intellectual disability and eyelid myoclonia with onset at age of 3 years, initially misinterpreted as tics.

Objective: To explore the genetic basis for a fetus with structural brain abnormalities.
Methods: The karyotypes of the fetus and its parents were analyzed by conventional G-banding. Chromosome microarray analysis (CMA) was carried out to detect chromosomal microdeletion and microduplication.

Xq25 microduplication syndrome is a recognized syndrome presenting intellectual disability and distinctive facial appearance. We generated an induced pluripotent stem cell (iPSC) line from peripheral blood mononuclear cells (PBMCs) of an 8-year-old boy with Xq25 Microduplication Syndrome carrying a 1.3 Mb hemizygote duplication at chrXq25.

Next generation genomic technologies have made a significant contribution to the understanding of the genetic architecture of human neurodevelopmental disorders. Copy number variants (CNVs) play an important role in the genetics of intellectual disability (ID). For many CNVs, and copy number gains in particular, the responsible dosage-sensitive gene(s) have been hard to identify.
