Figure 4.

Progression of somatic mutations in 12 patients with loss of chromosome Y. Striped bars represent a pathological diagnosis of no dysplasia or minimal dysplasia, while solid bars represent pathological diagnosis of myelodysplastic syndrome (Each alphabet letter corresponds to one patient). The height of bars represents the percentage of metaphases with loss of chromosome Y. Black dots on bars highlight number of mutations identified for the corresponding samples. LOY: loss of Y chromosome.
