20p12.3 microdeletion syndrome is a recently described syndrome characterized by Wolff-Parkinson-White syndrome (see this term), variable developmental delay and facial dysmorphism.
It has been clinically and molecularly characterized in 3 patients.
Dysmorphic features include macrocephaly, hypertelorism, down-slanting palpebral fissures and microstomia.
This syndrome is caused by an interstitial deletion encompassing 20p12.3. All these deletions except one occurred de novo and were characterized by comparative genomic hybridization (CGH) microarray and fluorescence in situ hybridization (FISH). They have a variable size with the smallest region of overlap including only one gene, BMP2 , which is a good candidate gene for explaining the phenotype of Wolff-Parkinson-White syndrome.
