Also, two SNPs in the CNTF (rs10758268 and rs7044318) gene were associated with inattentive symptom severity in ADHD and SNPs within cytokine genes IL-16 (rs8039027), and S100B (rs2839361) moderated the association between birthweight and symptom severity [115]. The gene discussed is CNTF; the disease is attention deficit-hyperactivity disorder.
