Moreover, as noted in the preceding paragraphs, unfavorable alleles of these three IL7R polymorphisms (rs6897932 C, rs987106 T, and rs3194051 A) have been related to low CD4+ T-cells and rapid AIDS progression in Caucasian naïve HIV infected patients [13] and slower CD4+ recovery in patients on cART [14, 39]. The gene discussed is CD4; the disease is AIDS.
