SLC11A1 and HIV infectious disease: For example, the genotypes of SLC11A1, a proton-coupled metal ion transporter, have determining effects on mortality in HIV infection [35]; SNPs of loci in or near SLC26A7, a multifunctional anion exchanger linked to energy metabolism and immunoregulations, are strongly associated with upper trunk and arm subcutaneous adipose tissue (SAT) distribution in antiretroviral therapy (ARV)- treated HIV-infected patients [36].
