Interestingly, the X253R mutant fully abolished the aggregatory propensity of βB1- and βA3/βB1-crystallins at high temperatures, suggesting that X253R was an aggregation-inhibition mutation of β-crystallin homomers and heteromers in dilute solutions. [biochemj.org]

Prognosis The prognosis for vision depended on the phenotype of the better eye Microphthalmos with cyst has the worst prognosis Coloboma with microcornea and microphthalmos a poor prognosis Coloboma with only microcornea has an intermediate prognosis [slideshare.net]

Etiology
Etiology Microcornea is a congenital abnormality. Overgrowth of the anterior tips of the optic cup during eye development has been proposed to result in a smaller than normal corneal size (Gupta and Kim 2010; Waheed and Azar 2005). [link.springer.com]
Etiology There is marked genetic heterogeneity. Mutations have been described in several crystallin genes ( CRYAA, CRYBB1, CRYGD ), and in the gap junction protein alpha 8 gene ( GJA8 ). [rarediseases.info.nih.gov]
Epidemiology
The anomalies are organized by anatomical system and presented in a consistent manner, including details of the clinical presentation, epidemiology, embryology, treatment and prevention for each anomaly. [books.google.de]
Epidemiology To date, more than 15 families showing microcornea-cataract syndrome have been described. [rarediseases.info.nih.gov]
Pathophysiology
Pathophysiology In the normal eye, optic fissure closes 33 to 40 days after conception. [slideshare.net]
Prevention
The anomalies are organized by anatomical system and presented in a consistent manner, including details of the clinical presentation, epidemiology, embryology, treatment and prevention for each anomaly. [books.google.de]
Currently, Cataract Microcornea Syndrome may not be preventable, since it is a genetic disorder. [dovemed.com]
Early cataract surgery in microcornea/microphthalmia eyes is essential to prevent amblyopia and improve visual outcomes, including stereopsis. [clinicaltrials.gov]
