Three individuals with these features have recently been reported and the responsible gene mutation has been found.
Children with this condition are born with distinctive facial features and palatal malformations. They are usually mentally and physically delayed with slow maturation of speech and locomotion. Eyebrow and scalp hair anteriorly may be sparse and the lid openings slant downward. The nasal bridge appears widened and the eyes seem to be farther apart. The eyelids droop (ptosis) and there may be misalignment of the eyeballs (strabismus).
The teeth are often malformed with a conical shape and have abnormally wide spacing. Males can have genital anomalies including undescended testicles. The fingers may be short (the thumbs in particular) and tapering. Various nonspecific brain defects have been found on imaging. Children may have poor muscle tone (hypotonia).
A gene mutation has been found to be associated with this condition. It is found in a pattern that would be expected to follow an autosomal dominant pattern of inheritance but parent-to-child transmission has not been reported.
Diagnosis of this syndrome is complex as most of the features also occur in other conditions. Genotyping is necessary to confirm the diagnosis which can only be suspected clinically. Nothing is known about longevity but quality of life is significantly impaired and most individuals require supportive care.
