Iris coloboma, ptosis, hypertelorism, and mental retardation: Baraitser-Winter syndrome or Noonan syndrome?
نویسنده
چکیده
Three children have been reported with a combination of iris coloboma, ptosis, hypertelorism, and growth and mental retardation with possible autosomal recessive inheritance. We report a single case whose clinical features encompass this syndrome and Noonan syndrome, and discuss the possible interpretations of this complex phenotype.

The syndrome combines facial and cerebral malformations. Facial malformations totall...
