چکیده

PURPOSE Here, we present two patients with congenital anterior staphyloma, with mutations in the CYP1B1 gene. METHODS We reviewed the medical records, including the genetic analysis. RESULTS Two unrelated patients presented with congenital anterior staphylomas. Both patients showed mutations in the CYP1B1 gene. The first patient, the product of a consanguineous marriage, showed a homozygous misssense mutation g.3987G>A (p.G61E). The second patient had compound heterozygous misssense mutations [g.4160 G>T (p.A119S) and g.8131 C>G (p.L432V)]. CONCLUSION CYP1B1 gene mutation may be associated with congenital anterior staphylomas.

Axenfeld-Rieger Syndrome Associated with Congenital Glaucoma and Cytochrome P4501B1 Gene Mutations

Developmental anomalies of the ocular anterior chamber angle may lead to an incomplete development of the structures that form the conventional aqueous outflow pathway. Thus, disorders that present with such dysfunction tend to be associated with glaucoma. Among them, Axenfeld-Rieger (ARS) malformation is a rare clinical entity with an estimated prevalence of one in every 200,000 individuals. T...

Genotype and phenotype correlations in congenital glaucoma.

PURPOSE To determine whether there is a correlation among mutations in the cytochrome P450 1B1 gene (CYP1B1), the degree of angle dysgenesis observed histologically, and disease severity in congenital glaucoma. METHODS Direct DNA sequencing was utilized to screen six unrelated children with congenital glaucoma, each set of parents, and all siblings for CYP1B1 mutations. Specimens of the anter...

Founder mutations of CYP1B1 gene in patients with congenital glaucoma from the United States and Brazil.

P rimary congenital glaucoma is an important cause of childhood blindness worldwide. In congenital glaucoma, the anterior segment of the eye fails to develop completely; this results, in particular, in malformation of the trabecular meshwork and aqueous outflow pathways. 2 Although sporadic cases arise frequently, many cases of congenital glaucoma are inherited as an autosomal recessive trait, ...

Multiple CYP1B1 mutations and incomplete penetrance in an inbred population segregating primary congenital glaucoma suggest frequent de novo events and a dominant modifier locus.

Primary congenital glaucoma (PCG) is an autosomal recessive disorder associated with unknown developmental defect(s) in the anterior chamber. Recently, we reported three distinct mutations in CYP1B1, the gene for cytochrome P4501B1, in 25 Saudi families segregating PCG. For this report, we analyzed 37 additional families and confirmed the initial finding of decreased penetrance. Mutations and i...
