Orofaciodigital syndromes (OFD) are a heterogeneous group of rare developmental disorders with a prevalence of approximately 1:50,000 live births. OFD are characterized by facial, oral, and finger anomalies. However, a wide range of additional features affecting the central nervous system and visceral organs such as the kidney, liver, and pancreas have also been observed, leading to the clinical differentiation of various OFD subtypes. The subtypes generally follow an autosomal recessive inheritance pattern. The most common form of OFD (OFD type 1), though, is inherited in an X-linked pattern and embryonically lethal in the males. Only a subset of OFD type 1 cases show a familial pattern of inheritance; the majority of pathogenic changes (approximately 75%) occur sporadically.
