FIG. 2.

Pedigree of the GLC1C family. Below the symbol is the identification number of those family members for whom we have DNA and/or clinical information. Below the identification number is the IL-20R2 genotype (C/T indicates IL-20R2 mutation, C/C indicates normal IL-20R2 genotype) and age of last exam or age of diagnosis, if they have primary open angle glaucoma (POAG). No DNA was available for individual 2004; therefore, the IL-20R2 genotype is not listed. The left upper corner is black if they have been diagnosed with POAG. A black dot in the middle of the symbol indicates that they are a suspect. The genotype is not shown for those individuals for whom we have no DNA sample.
