Rearrangement of NUTM1 gene (NUTM1r) is one of the most frequent aberrations occurring in infants (younger than 1 year at diagnosis) with B‐cell precursor Acute Lymphoblastic Leukaemia (BCP‐ALL). In this study we had the unique opportunity to analyze the umbilical cord blood (UCB) sample from one infant patient with NUTM1r BCP‐ALL. Herein we reported for the first time that NUTM1r infant ALL arise prenatally, as both the patient‐specific CUX1::NUTM1 fusion gene, as well as two IG/TR leukaemic markers were already present and detectable in the patient's UCB at birth. Our results clearly demonstrate the prenatal origin of NUTM1r infant BCP‐ALL.
