Only two genes, STK32A (treated HAND: d-score: 3.767, fold change:1.965, q: 0.001, AD: d-score: 3.532, fold change: 1.554, q: < 0.001) and CD24 (cART treated HAND: d-score: −4.079, fold change: 0.0984, q: < 0.001; AD: d-score: 3.460, fold change: 2.081, q: < 0.05), were found to be common DEGs between cART treated HAND and AD respectively. The gene discussed is STK32A; the disease is Alzheimer disease.
