DCC and age-related macular degeneration: Others have shown combined effects of sequence variants in DCC with loci in 1q31 and 10q26 highlighted by the AGC—in the period during which the present report was under revision Riveros et al. published results from an exhaustive genome-wide interaction analysis involving 137,467,878 tests for AMD-associated SNPs.[10] From this work a DCC-resident SNP (rs9966348) emerged in a set of 19 highly interconnected DNA sequence variants manifesting significant interactions of the highest magnitude.
