Ectopia lentis has rarely been reported to occur in association with craniosynostosis, and this was found only in sporadic cases. We report on twin sisters who underwent surgery for craniosynostosis and later on, at age 3 years, were found to have bilateral ectopia lentis. Molecular studies yielded a probability of monozygosity of more than 0.98. Inheritance of the syndrome may be autosomal dominant, possibly due to a new mutation, autosomal recessive, or X-linked with male lethality.

Primary ciliary dyskinesia (PCD) is a genetic disease characterized by abnormal ciliary structure and function, impaired mucociliary clearance, and chronic middle ear, sinus, and lung disease.

We report on male monozygotic twins with 22q11.2 deletion and discordant phenotypes. The twins had twin-to-twin transfusion syndrome. Twin 1, the smaller of the pair, had Tetralogy of Fallot, a characteristic facial appearance, swallowing dysfunction, anal atresia, short stature, and mental retardat
We report on a pair of monozygotic twins with probable Baller-Gerold syndrome (BGS). Twin A had severe coronal craniosynostosis. Twin B had right radioulnar and ipsilateral first metacarpal hypoplasia. Both had bilateral fifth finger clinodactyly. Assuming that the twins were truly monozygotic, a si
