The results from Sean's bone marrow biopsy came back last week. Of the 20 cells they analyzed, 3 showed an abnormality in chromosome 1.  Fortunately chromosome 1 changes are considered "benign" and not "clinically significant".  Some people have chromosome 1 abnormalities for many years without issues.  However, it is a "change in the marrow", so we plan to repeat the bone marrow biopsy in about 6 months.  

This is the first time we have seen an abnormality in Sean's bone marrow.  Changes in chromosome 3 or 7 are the ones we worry about.  They are precursors to leukemia. If those appear, then we would need to consider going to transplant in short order.  We aren't too concerned at this point.  It's just another thing to to put on our radar to monitor.  We will provide an update after his next biopsy in the late summer.

As always...thanks for all the prayers, love and support. - Sean, Kelsey, Lorraine and Kevin!
