We did not find an association between HIV-disease severity markers, such as CD4+ T-cell, log HIV VL zenith and having an AIDS diagnosis, and IQ and cognitive profile by MNC (p>0.477), nor did we find an association between cART-related factors, such as age at cART initiation and time between diagnosis and cART initiation and intellectual and cognitive profile by MNC (all p>0.380). The gene discussed is CD4; the disease is AIDS.
