Among the top 34 single-nucleotide polymorphisms (SNPs) (p < 1 x 10⁻⁶), two loci had concordant effects in both cohorts: ALOX15B (rs1804772) (MAF: 1%; p = 3.95 x 10⁻⁷) that influences arachidonic acid metabolism and thus platelet aggregation, and KALRN (rs570684) (MAF: 1%; p = 4.34 x 10⁻⁷) that has been previously associated with risk of ischemic stroke, atherosclerosis, and early-onset coronary artery disease. Conclusion: This represents the largest GWAS meta-analysis conducted to date associating SNPs to VTE in children and adolescents treated on childhood ALL protocols. Validation of these findings is needed and may then lead to patient stratification for VTE preventive interventions. As VTE hemostasis involves multiple pathways, a more powerful GWAS is needed to detect combination of variants associated with VTE.]]> Wed 20 Jul 2022 14:36:48 AEST ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:46592 n = 33). SNP-microarray analysis identified additional aberrations in 97% of patients (32/33) compared to conventional techniques. This changed the genomic risk category of 24% (8/33) of patients. Additionally, 27% (9/33) of patients exhibited a ‘hyperdiploid’ genome, which is generally associated with a good genomic risk and favourable outcomes. An enrichment of IKZF1 deletions was observed with one third of the cohort affected. Our findings suggest the current classification system could be improved and highlights the need to use more sensitive techniques such as SNP-microarray for cytogenomic risk stratification in B-ALL.]]> Fri 25 Nov 2022 15:04:02 AEDT ]]> https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:44512 Fri 14 Oct 2022 09:11:36 AEDT ]]>
