Absence of SIX6 mutations in microphthalmia, anophthalmia, and coloboma.
PURPOSE To investigate whether 173 patients with microphthalmia, anophthalmia, and coloboma have mutations in the eye-development gene SIX6. METHODS The two exons of the SIX6 gene were amplified by PCR from patients' genomic DNA and directly sequenced to search for mutations. The PCR products of 75 patients were also analyzed by denaturing high-performance liquid chromatography (DHPLC). RES...
متن کاملMicrophthalmia, anophthalmia, and coloboma and associated ocular and systemic features: understanding the spectrum.
IMPORTANCE Microphthalmia, anophthalmia, and coloboma form an interrelated spectrum of congenital eye abnormalities. OBJECTIVE To document the ocular and systemic findings and inheritance patterns in patients with microphthalmia, anophthalmia, and coloboma disease to gain insight into the underlying developmental etiologies. DESIGN, SETTING, AND PARTICIPANTS This retrospective consecutive c...
متن کاملNational study of microphthalmia, anophthalmia, and coloboma (MAC) in Scotland: investigation of genetic aetiology.
We report an epidemiological and genetic study attempting complete ascertainment of subjects with microphthalmia, anophthalmia, and coloboma (MAC) born in Scotland during a 16 year period beginning on 1 January 1981. A total of 198 cases were confirmed giving a minimum live birth prevalence of 19 per 100 000. One hundred and twenty-two MAC cases (61.6%) from 115 different families were clinical...
متن کاملAnophthalmia and microphthalmia
Anophthalmia and microphthalmia describe, respectively, the absence of an eye and the presence of a small eye within the orbit. The combined birth prevalence of these conditions is up to 30 per 100,000 population, with microphthalmia reported in up to 11% of blind children. High-resolution cranial imaging, post-mortem examination and genetic studies suggest that these conditions represent a phe...
متن کاملSequence alterations in RX in patients with microphthalmia, anophthalmia, and coloboma
PURPOSE Microphthalmia, anophthalmia, and coloboma are ocular malformations with a significant genetic component. Rx is a homeobox gene expressed early in the developing retina and is important in retinal cell fate specification as well as stem cell proliferation. We screened a group of 24 patients with microphthalmia, coloboma, and/or anophthalmia for RX mutations. METHODS We used standard P...
