populationSaudi Arabia“Although PCG is often considered to be fully penetrant, the disease shows 50% penetrance in some Saudi Arabian families. METHODS: A genome-wide screen, a single nucleotide polymorphism (SNP) analysis in the TYR chromosomal region 11q13-q21, and sequencing of the TYR gene was performed with individuals from Saudi Arabian families with multiple, clinically confirmed, molecularly proven, nonpenetrant members. CONCLUSIONS: TYR is not a modifier of the CYP1B1-associated PCG phenotype in the Saudi Arabian population.”0.95saudi_context_rules_v1

The frequency of CYP1B1 mutations was comparatively lower than Saudi Arabian, Slovakian Gypsys, and Turkish populations, largely due to genetic heterogeneity and ethnic diversities in Indian populations.”0.95saudi_context_rules_v1

populationSaudi Arabia“Recently, we reported three distinct mutations in CYP1B1, the gene for cytochrome P4501B1, in 25 Saudi families segregating PCG. Eight distinct mutations were identified: G61E, R469W and D374N, the most common Saudi mutations, account for 72, 12 and 7%, respectively, of all the PCG chromosomes. The identification of eight distinct mutations in a single gene, on four distinct haplotypes, suggests a relatively recent occurrence of multiple mutations in CYP1B1 in Saudi Arabia. These data demonstrate decreased penetrance of the PCG phenotype in the Saudi population, because 40 apparently unaffected individuals in 22 families have mutations and haplotypes identical to their affected siblings.”0.95saudi_context_rules_v1

populationSaudi Arabia“Mutations in CYP1B1, the gene for cytochrome P4501B1, are the predominant cause of primary congenital glaucoma in Saudi Arabia. Homozygosity mapping with a DNA pooling strategy in three large consanguineous Saudi PCG families identified the GLC3A locus on chromosome 2p21 in a region tightly linked to PCG in another population. Formal linkage analysis in 25 Saudi PCG families confirmed both significant linkage to polymorphic markers in this region and incomplete penetrance, but it showed no evidence of genetic heterogeneity. Furthermore, the small number of PCG mutations identified in this Saudi population makes both neonatal and population screening attractive public health measures.”0.95saudi_context_rules_v1
