| A recently described syndrome with characteristics of Wolff-Parkinson-White syndrome, variable developmental delay and facial dysmorphism. 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 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. |
