E-MTAB-7729
Multiplexed DNA high throughput genotyping study to determine the mutational status of transient (TAM) and acute myeloid leukaemic (ML-DS) Down syndrome individuals.
We used a 48.48 Fluidigm Access Array approach (1070 Amplicons spanning 62 genes: 157kB coverage) of genomic DNA from over 100 samples to genotype individuals with transient abnormal myelopoiesis (TAM) and acute myeloid leukemia of Down syndrome (ML-DS).   Individually barcoded patient samples were subjected to paired-end 150bp sequencing (Illumina MiSeq), including paired GATA1 variant negative controls (including Post treatment) and 8 known reference GATA1- controls.  Samples were mapped to build 37 of the human reference genome and subject to bioinformatic analysis (Varscan, Pindel, GATK) to facilitate the characterisation of known gene mutations in cancer as well as the identification / validation of potentially novel variants.
