Summary Summary

The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.

Orpha Number: 2409

Disease definition

Lowry-MacLean syndrome is a very rare syndrome characterized by microcephaly, craniosynostosis, glaucoma, growth failure and visceral malformations.

Epidemiology

Only three cases have been reported in the literature in three unrelated families.

Clinical description

Dysmorphic features include trigonocephaly, exotropia, cleft palate, beaked nose and low-set ears. All the affected patients have associated congenital visceral malformations including congenital heart defects, diaphragmatic hernia, genital or cerebral abnormalities.

Genetic counseling

The demonstration of congenital glaucoma, hallmark of the syndrome, in the father of an affected patient, supports autosomal dominant inheritance.

Prognosis

Prognosis is poor.
