However, the mean number of absolute CD34+ cell in HD patients in this cohort was 0.49 ± 0.32 cells(/μl) as shown in our previous paper[18], which was much lower compared to that in non-HD patients without DM (mean CD34+ cell count 1.2 ± 0.1 cells (/μl) as reported in a previous study[22]. This evidence concerns the gene CD34 and Huntington disease.
