MLLT10 and axial length measurement: The PICALM::MLLT10 fusion gene, generated by chromosome aberration of t(10;11)(p12.3;q14.2), is a rare but recurrent event in acute leukemia (AL), which was identified in about 7% of patients with T‐cell acute lymphoblastic leukemia (T‐ALL) and other leukemia, associated with the upregulation of the proto‐oncogenic HOXA and MEIS1 genes and poor prognosis [1, 2, 3, 4].
