Two SNPs in <i>ADD3</i> were replicated as associated with BA (1.60E-04 ≤ <i>P</i>≤1.70E-04, 1.33 ≤ odds ratio (OR) ≤ 1.58 for rs17095355, 2.10E-04 ≤ <i>P</i>≤5.30E-04, 1.26 ≤ OR ≤ 1.57 for rs2501577).
This study suggests that the ADD3 gene plays an important role in BA pathogenesis and reveals a significant association between two SNPs, rs17095355 and rs10509906, and BA.
Though we failed to replicate the individual association of rs10509906 to disease, the intragenic epistatic effect between rs10509906 and rs2501577 was suggested as exhibiting susceptibility to BA, further cross-validated by multifactor dimensionality reduction (MDR) (<i>P</i>=0.068, OR = 1.37), which may explain extra hidden heritability of <i>ADD3</i> to BA.
This study suggests that the ADD3 gene plays an important role in BA pathogenesis and reveals a significant association between two SNPs, rs17095355 and rs10509906, and BA.
