NUCLEOLIN and deafness: Genes tagged by these SNPs were mainly cataloged into the following four gene sets9: (a) oxidative stress genes, such as CAT, SOD1 and SOD2; (b) inner ear potassium recycling pathway genes, such as KCNQ4 and KCNE1; (c) HSP genes, such as Hsp70; and (d) monogenic deafness genes, such as PCDH15 and MYH14. Recently, a genome‐wide association study (GWAS) in a European population consisting of 25 cases and 23 controls has revealed that one SNP (rs7598759) mapped in the nucleolin (NCL) gene was significantly correlated with the risk of NIHL.12
