CCL2 and sensorineural hearing loss disorder: With regard to the second SNP within the CCL2 gene (rs1024611) analysed in the present study, an increased frequency of AG and GG genotypes was found in infants with SNHL when compared to those with normal hearing at birth (OR = 3.06; 95% CI, 0.99–9.45, p = 0.046 and OR = 3.33; 95% CI, 1.05–10.62, p = 0.036, for unadjusted and adjusted regression model, respectively).
