Craniosynostosis-Anal Anomalies-Porokeratosis Syndrome

Craniosynostosis - anal anomalies - porokeratosis, or CDAGS, is a very rare condition characterized by craniosynostosis and clavicular hypoplasia, (C), delayed closure of the fontanel (D), anal anomalies (A), genitourinary malformations (G) and skin eruption (S).

Epidemiology

It has been described in seven patients from four unrelated families.

Clinical description

Cranial abnormalities include a coronal synostosis with wide-open anterior and posterior fontanels and large parietal foramina. In some patients the skin eruption has been classified as porokeratosis (a disorder of keratinization). Sensorineural hearing loss and mild to severe developmental delay are common.

Genetic counseling

The condition is transmitted as an autosomal recessive trait.
