Anophthalmia-Waardenburg syndrome with expanding phenotype: does neural crest play a role?
2007
We describe a child with bilateral anophthalmia, limb anomalies, skin lesions, cerebral malformations, epilepsy, and mental retardation. This patient, according to eponymous classification, should fit into the Anophthalmia-Waardenburg syndrome, although he also presents cutaneous and cerebral manifestations never reported in this syndrome until now. These clinical findings could be explained by the new classification of brain malformations, which takes into account the role of neural crest in Waardenburg syndrome.
ALDH1A3 Mutations Cause Recessive Anophthalmia and Microphthalmia
2013
Anophthalmia and microphthalmia (A/M) are early-eye-development anomalies resulting in absent or small ocular globes, respectively. A/M anomalies occur in syndromic or nonsyndromic forms. They are genetically heterogeneous, some mutations in some genes being responsible for both anophthalmia and microphthalmia. Using a combination of homozygosity mapping, exome sequencing, and Sanger sequencing, we identified homozygosity for one splice-site and two missense mutations in the gene encoding the A3 isoform of the aldehyde dehydrogenase 1 (ALDH1A3) in three consanguineous families segregating A/M with occasional orbital cystic, neurological, and cardiac anomalies. ALDH1A3 is a key enzyme in the…
