Orofaciodigital syndrome type 2 (OFDS 2) is a genetic condition that affects the development of the mouth, face, hands, and feet. It belongs to a group of disorders called orofaciodigital syndromes (OFDS), which are characterized by mouth malformations, unique facial findings, and abnormalities of the fingers and/or toes. Other organs might be affected in OFDS, defining the specific types. OFDS type 2 is very similar to oral-facial-digital syndrome (OFDS) type 1. Signs and symptoms may include: cleft lip and/or palate, additional or fused fingers or toes (polydactyly or syndactyly), characteristic facial features, and congenital heart defects. Although it is highly suspected that OFDS 2 is genetic, the exact gene that causes the syndrome has not been identified. It is believed to be inherited in an autosomal recessive pattern. Although there is no specific treatment or cure for OFDS 2, there are ways to manage the symptoms. A team of doctors or specialists is often needed to figure out the treatment options for each person.

OFDS 2 is suspected to be a genetic disorder, given reports of families in which it appears to be inherited in an autosomal recessive inheritance pattern. The causative gene is not known at this time.

• Facial findings including nodules (bumps) of the tongue, a split in the lip and/or palate (cleft lip and/or palate), a thickened frenulum (cord of tissue) under the tongue or between the lip and gum, and an unusually wide nasal bridge resulting in widely spaced eyes (dystopia canthorum)
• Finger and toe findings including narrow, short fingers and toes (clinobrachydactyly), syndactyly (fused fingers and toes), presence of more than five fingers on hands and/or five toes on feet (polydactyly), and a Y-shaped central metacarpal (bone that connects the fingers to the hands)

Other possible findings include: conductive hearing loss, central nervous system impairments (porencephaly and hydrocephaly), intellectual disabilities, increased susceptibility to respiratory (lung) infections, and heart defects (atrioventricular canal [endocardial cushion] defects).

Although there is no one treatment for OFDS 2, there may be ways for a team of specialists to manage the signs and symptoms present in each individual. For example, reconstructive surgery might be performed to correct oral, facial, and/or finger and toe abnormalities.

The signs and symptoms associated with OFDS 2 may vary from person to person, even within the same family. Therefore, the challenges faced by one person with the syndrome may be completely different than someone else with OFDS 2. Given the variability of the disorder, it may be useful to speak with the patient's health care provider in order to have a better understanding of the different complications that might arise based on the signs and symptoms present in that patient.
