There is one clinical trial.
Primary congenital glaucoma patients and their immediate relatives will undergo complete ophthalmic examination and an interview with a geneticist. A blood sample will be drown from all participants for DNA analysis. The CYP1B1 gene coding sequences will be screened for all individuals. If no mutation or only one heterozygous mutation will be found in the CYP1B1 gene, screening for MYOC gene mutations will be performed.
Jewish families had compound heterozygous mutations, i.e. an Ashkenazi family had mutations in the CYP1B1 gene (Arg368His and R48G, A119S and L432V haplotypes), and an Ashkenazi-Sephardic family had a mutation on the CYP1B1 gene (1908delA, Sephardic) with a second missense mutation on the MYOC gene (R76K, Ashkenazi). --- Arg368His --- --- R48G --- --- A119S ---
Description: Mutations in the CYP1B1 gene were detected in 12 of 26 (46%) families with PCG (5 Muslim Arab, 5 Druze, 2 Jewish). Jewish families had compound heterozygous mutations, i.e. an Ashkenazi family had mutations in the CYP1B1 gene (Arg368His and R48G, A119S and L432V haplotypes), and an Ashkenazi-Sephardic family had a mutation on the CYP1B1 gene (1908delA, Sephardic) with a second missense mutation on the MYOC gene (R76K, Ashkenazi). Muslim Arabs and Druze tended to have a more severe phenotype than did the Jews.
