Abstract:
PURPOSE: A biomarker for leukemia in children and a method for predicting the risk of leukemia in children are provided to check the genetic character of an individual and to diagnose risk. CONSTITUTION: A marker for diagnosing leukemia in children contains: a polynucleotide containing 8-200 serial base sequences with an SNP of rs703817, rs17433222, or rs3794845; or a complement thereof. A kit for diagnosing leukemia in children contains the marker. A method for diagnosing leukemia in children comprises: a step of preparing nucleic acid samples from a test sample; a step of determining the base sequence of an SNP of rs703817, rs17433222, or rs3794845 in the nucleic acid sample; and a step of determining the risk of leukemia in case that rs703817, rs17433222, and rs3794845 is GG, GG, and CC, respectively.
