By analysing tumour DNA from patients with sporadic T - cell prolymphocytic leukaemia ( T - PLL ) , a rare clonal malignancy with similarities to a mature T - cell leukaemia seen in A - T , we demonstrate a high frequency of ATM mutations in T - PLL .
 Disease: tumour; Disease: sporadic T - cell prolymphocytic leukaemia; Disease: T - PLL; Disease: clonal malignancy; Disease: mature T - cell leukaemia; Disease: A - T; Disease: T - PLL
