Anterior segment dysgenesis disorders and their molecular genetic cause
 Moravíková, Jana ; Lišková, Petra (advisor) ; Krulová, Magdaléna (referee)
Proper eye development depends on expression and mutual regulation of many genes. Anterior segment dysgenesis (ASD) are a highly heterogeneous group of diseases exhibiting all types of Mendelian inheritance, which manifest as combination of congenital abnormalities of the cornea, iris, anterior chamber angle or lens. Screening of genes associated with ASD does not often lead to the identification of the underlying genetic cause implying that there are still novel variants or genes to be discovered. Molecular genetic analysis in 12 probands with ASD using Sanger and whole-exome sequencing were performed. Functional analysis by Exon trapping assay was provided in variants predicted to effect pre-mRNA splicing. Four PAX6 mutations evaluated as pathogenic or likely pathogenic in a heterozygous state were found in four probands c.183C˃G; p.(Tyr61*), c.1032+1G>A, c.1183+1G>T and c.622C>T; p.(Arg208Trp). One proband was found to be a compound heterozygote for c.244A>G; p.(Met82Val) and c.541delG; p.(Glu181Lysfs*26) mutations in FOXE3. In 7 probands, no potentially pathogenic variants were identified. Exon trapping assay confirmed that mutations c.1032+1G>A and c.1183+1G>T have an effect on pre-mRNA splicing of the PAX6 gene. Detailed molecular-genetic analysis in patients with ASD may contribute to...
