摘要: Somatic mutations affecting ETV6 often occur in acute lymphoblastic leukemia (ALL), the most common childhood malignancy. The genetic factors that predispose to ALL remain poorly understood. Here we identify a novel germline p. L349P mutation kindred affected by thrombocytopenia and ALL. A second N385fs was identified an unrelated characterized thrombocytopenia, secondary myelodysplasia/acute myeloid leukemia. Leukemic cells from proband showed deletion of wild type with retention N385fs. Enforced expression mutants revealed normal transcript protein levels, but impaired nuclear localization. Accordingly, these exhibited significantly reduced ability regulate transcription target genes. Our findings highlight role for predisposition.
