Background: Acute leukemia in early age (EAL) is characterized by acquired genetic alterations such as MLL rearrangements (MLL-r). The aim of this case-controlled study was to investigate whether single nucleotide polymorphisms (SNPs) of IKZF1, ARID5B, and CEBPE could be related to the onset of EAL cases (<24 months-old at diagnosis).
Methods: The SNPs (IKZF1 rs11978267, ARID5B rs10821936 and rs10994982, CEBPE rs2239633) were genotyped in 265 cases [169 acute lymphoblastic leukemia (ALL) and 96 acute myeloid leukaemia (AML)] and 505 controls by Taqman allelic discrimination assay.
Article Synopsis
- The study looked at how babies that grow really fast in the womb might be linked to a higher chance of getting a type of cancer called acute lymphoblastic leukemia (ALL) when they are kids.
- Researchers combined data from 12 different studies to see if babies who were bigger than expected for their age at birth had a greater risk of this cancer.
- They found that babies who were larger for their gestational age had about a 24% higher risk of getting ALL, while smaller babies had a lower risk, and the results were similar no matter the child's sex or background.
NQO1 rs1800566 (C609T), PON1 rs662 (Q192R), and PON1 rs854560 (L55M) polymorphisms segregate the risk of childhood acute leukemias according to age range distribution.

Purpose: The risk of developing childhood leukemia has been associated with gene polymorphisms that decrease the activity of detoxifying metabolic enzymes and enzymes involved in systemic oxidative stress. We investigated the NQO1 and PON1 polymorphisms for associations with susceptibility to childhood leukemia.
Methods: Samples from 1,027 Brazilian children (519 acute lymphoblastic leukemia, ALL; 107 acute myeloid leukemia, AML; 401 controls) were analyzed.
Seven single nucleotide polymorphisms (SNPs) were genotyped in 535 Brazilian children (158 with acute lymphoblastic leukemia [ALL], 74 with acute myeloid leukemia [AML] and 303 controls). The subjects were classified as fast or slow acetylators based on their genotypic variants. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals.

N-Acetyltransferase 2 (NAT2) enzyme acetylates dipyrone, resulting in a detoxified metabolite. We performed genotyping to identify the distribution of NAT2 polymorphisms in duo samples from mothers and children previously investigated in a case-controlled study of IL.
