Cleidocranial dysplasia: clinical and molecular genetics.

abstract：BACKGROUND:Orofacial cleft (OFC) is the most prevalent craniofacial birth defect. Genes involved in one-carbon, folate and vitamin B12 metabolisms have been associated with OFC but no study performed a concomitant assessment on genes involved in these three pathways. OBJECTIVE:We looked for potential genetic variants ...
