Presentation
(Age and Sex Distribution) The incidence of Chromosome 2q23.1 Microdeletion Syndrome is presently unknown. [dovemed.com]
In this study, we demonstrate that MBD5 is the only gene in common among all duplication cases and that overexpression of MBD5 is likely responsible for the core clinical features present in 2q23.1 microduplication syndrome. [ohsu.pure.elsevier.com]

Prognosis
What is the Prognosis of Chromosome 2q23.1 Microdeletion Syndrome? (Outcomes/Resolutions) The prognosis of Chromosome 2q23.1 Microdeletion Syndrome is dependent upon the severity of the signs and symptoms and associated complications, if any. [dovemed.com]

Prevention
How can Chromosome 2q23.1 Microdeletion Syndrome be Prevented? Chromosome 2q23.1 Microdeletion Syndrome may not be preventable since many of these genetic disorders are diagnosed at or following the birth of the child. [dovemed.com]
