Deletion of 18p syndrome is characterized by dysmorphic features, growth deficiencies, and mental retardation with a poor verbal performance. Until now, few families have been described with limited clinical description. We report transmission of deletion 18p from a mother to his son. The proband is 8 years old and has short stature, dysmorphic features, polymorphous dyslalia and moderate menta...

The Lujan-Fryns syndrome or X-linked mental retardation with marfanoid habitus syndrome is a syndromal X-linked form of mental retardation, affecting predominantly males. The prevalence is not known for the general population. The syndrome is associated with mild to moderate mental retardation, distinct facial dysmorphism (long narrow face, maxillary hypoplasia, small mandible and prominent for...
