This MR analysis suggests that CD66b++ myeloid cell AC, HLA DR on CD14- CD16 + monocyte, IgD on unsw mem, CD4 on CD4+, CD24 on IgD + CD38-, CD20 on CD24 + CD27+, CD19 on CD20-, CD62L- CD86 + myeloid DC %DC, HLA DR + CD4 + AC, and EM CD8br AC are associated with increased genetic susceptibility to HF. The gene discussed is CD27; the disease is hydrops fetalis.
