• Acute lymphoblastic leukemia (ALL) is the most common childhood cancer in the world. Single nucleotide variants (SNVs) in miRNA and genes encoding proteins of the miRNA synthesis complex (SC) may affect the processing of drugs used in the treatment of ALL, resulting in treatment-related toxicities (TRTs). We investigated the role of 25 SNVs in microRNA genes and genes encoding proteins of the miRNA SC, in 77 patients treated for ALL-B from the Brazilian Amazon. The 25 SNVs were investigated using the TaqMan OpenArray™ Genotyping System. SNVs rs2292832 ( ), rs2043556 ( ), and rs10505168 ( ) were associated with an increased risk of developing Neurological Toxicity, while rs2505901 ( ) was associated with protection from this toxicity. (rs10505168) and (rs56103835) were associated with protection from gastrointestinal toxicity, while (rs639174) increased the risk of development. The rs2043556 ( ) variant was related to protection from infectious toxicity. SNVs rs12904 ( ), rs3746444 ( ), and rs10739971 ( ) were associated with a lower risk for severe hematologic toxicity during ALL treatment. These findings reveal the potential for the use of these genetic variants to understand the development of toxicities related to the treatment of ALL in patients from the Brazilian Amazon region.
