title: Unknown dysmorphic syndromes and development delay in Saudi Arabia.
abstract: Forty-four Saudi Arabian patients with unknown dysmorphic syndromes were studied with respect to their level of cognitive delay. The relationship between such delay and particular patterns of dysmorphic features, as well as various demographic and historical data, were also investigated. Prognostication and genetic counseling are difficult for this group because little is known about morbidity or other factors. These concerns, along with broader issues, stimulated this study. Significant associations were found between level of cognitive function and consanguinity, abnormal motor and language milestones, and abnormal electroencephalograms. No significant relationship was found between various dysmorphic feature clusters and measured cognition. Concerns were expressed about demands on family and community for these children, as well as possible larger issues in this heavily consanguineous society. Further research, including epidemiologic studies, was recommended.
