Filippi syndrome is present at birth and impacts the development of the head, face, and limbs. Signs and symptoms include a small head (microcephaly), webbing of the fingers and toes (syndactyly), intellectual disability, growth delay, and distinctive facial features (high and broad nasal bridge, thin nostrils, small chin or micrognathia, and a high frontal hairline). Other features may can include vision problems, extra fingers and toes, and seizures. Because Filippi syndrome is very rare, it is not known how this condition changes over time. Filippi syndrome is caused by a genetic variant in the CKAP2L gene and is inherited in an autosomal recessive pattern. Diagnosis is based on the symptoms, clinical exam, and may be confirmed by the results of genetic testing. Treatment is focused on managing the symptoms.
