- Primary open-angle glaucoma (POAG) is genetically heterogeneous, with 6 named POAG loci GLC1A-F mapped and genes myocilin (MYOC) and optineurin (OPTN) identified at 2 of the loci. Using penetrance-model-free methods, we screened the POAG loci GLC1A-F in an extended Australian pedigree, using 3-5 markers within each locus. p values of less than 0.05 were obtained empirically using SimWalk2 and exactly using Genehunter for 2 markers within the GLC1B region on chromosome 2. Fine mapping of this region produced p values of 0.01 or less at 5 markers flanked by D2S1897 and D2S2269. The 9 cM haplotype of interest overlaps the original GLC1B region. These results provide supportive evidence for the GLC1B locus on chromosome 2cen-q13 and verify the existence of POAG susceptibility gene in this region, increasing the likelihood of gene identification.
