Imputation of SNPs associated with presbycusis through linkage disequilibrium analysis in the ILDR1 gene.

The single-nucleotide polymorphisms (SNP) ILDR1 rs2332035 has shown a high statistical association with presbycusis (hearing loss with age or age-related hearing impairment (ARHI)), according to genetic association studies in European populations. However, linked markers have not been surveyed. Here linkage disequilibrium (LD) of markers in ILDR1, in relation to rs2332035, is explored in the 2504 individuals from the 1000Genomes database. Of the 920 SNPs retrieved, 10 showed strong LD (r2= 0.8) in Europeans and Latin Americans, which are proposed here as candidate markers for both control-case association and cause-effect studies in both populations.
