Haplotype frequencies in the 3’ end of the PRPH2 gene in ABCA4 disease cohorts and genetically determined disease subgroups.

For PRPH2, nucleotide positions and protein translation correspond to CCDS4871.1 and NP_000313.2, respectively; for ABCA4, CCDS747.1 and NP_000341.2, respectively. Nucleotide numbering uses the A of the ATG translation initiation start site as nucleotide 1. The haplotype frequencies were determined directly from sequence data.
