Purpose: To screen the myocilin (MYOC) and forkhead box protein C1 (FOXC1) genes for sequence variations in primary congenital glaucoma (PCG). Methods: Seventy five PCG patients were screened for MYOC variations and 54 cases (negative or heterozygous for cytochrome P4501B1 mutations) for FOXC1 mutations by polymerase chain reaction (PCR) and DNA sequencing. Results: Five single nucleotide polymorphisms (SNPs; -126T>C, -83G>A, p.R76K, IVS2+35G>A, and p.Y347Y) were identified in MYOC and two sequence variations (GGC375ins and GGC447ins) in FOXC1. No pathogenic variations were identified in MYOC and FOXC1 in our patients. Conclusions: MYOC and FOXC1 mutations are not involved in pathogenesis of primary congenital glaucoma in our patients. Thus, it is important to screen other loci for involvement in congenital glaucoma in cases which are negative or heterozygous for CYP1B1 mutations to have a better insight in to disease pathogenesis.
