Spectrum of clinical features associated with interstitial chromosome 22q11 deletions: a European collaborative study.

abstract：BACKGROUND:Genomic imprinting is a process causing genes to be expressed according to parental origin. Imprinting acts to coordinate fetal and prenatal growth, as well as control postnatal adaptations. Studies on human imprinting are confounded by tissue availability, sampling variability and limitations posed by tissu...
