We estimate the allele frequencies of two single nucleotide polymorphisms (1410 C → T) and (1521 A → C) in the coding region of PAX2. The coding region single nucleotide polymorphisms (cSNPs) were identified by sequencing of amplimers of PAX2 exon 8 exhibiting variant migration patterns in the course of genomic DNA mutation screening from patients with renal- coloboma syndrome. Allele frequencies of the two polymorphisms were 0.94 for 1410C and 0.72 for 1521A. Cosegregation analyses of both alleles suggest that they are each in Hardy-Weinberg equilibrium and jointly in linkage equilibrium and may represent ancient polymorphisms. Characterization of PAX2 exon 8 cSNPs will serve as useful tools for mapping at the PAX2 locus.
