ABSTRACT

The combination of lagophthalmia, euryblepharon, ectropion of lower eyelids, distichiasis, bilateral cleft lip and palate, and oligodontia comprises the blepharo-cheilo-dontic (BCD) syndrome. This combination has been found sporadically or with positive family history and inherited as an autosomal dominant condition with variable expression. We described a Saudi boy with the cardinal signs consistent with the BCD syndrome. In addition to the common components of BCD syndrome that involve eyelids, lip, and teeth abnormalities, this patient is the third reported BCD case with imperforate anus, the second with thyroid agenesis, and the first with lumbosacral meningomyelocele.

ABSTRACT

Raine syndrome is an autosomal recessive disorder caused by mutations in the FAM20C gene that is characterized by generalized osteosclerosis with periosteal new bone formation and distinctive craniofacial dysmorphism. We report on a child who is homozygous for a 487-kb deletion in 7p22.3 that contains FAM20C. Both parents were heterozygous for the deletion. Our patient had the common craniofacial features as well as, uncommon features such as protruding tongue, short stature, and hypoplastic distal phalanges. In addition, he had wormian bones and pyriform aperture stenosis, features that are usually under diagnosed. It is clear that Raine syndrome has a wide range of expression and may not be lethal in the neonatal period. Furthermore, Raine cases due to whole gene deletion do not seem to have a major difference in the phenotype over those caused by various mutations.
