Myelodysplastic syndromes (MDS) are uncommon in children and have a poor
prognosis. In contrast to adult MDS, little is known about the genomic landscape
of pediatric MDS. Here, we describe the somatic and germline changes of pediatric
MDS using whole exome sequencing, targeted amplicon sequencing, and/or
RNA-sequencing of 46 pediatric primary MDS patients. Our data show that, in
contrast to adult MDS, Ras/MAPK pathway mutations are common in pediatric MDS
(45% of primary cohort), while mutations in RNA splicing genes are rare (2% of
primary cohort). Surprisingly, germline variants in SAMD9 or SAMD9L were present
in 17% of primary MDS patients, and these variants were routinely lost in the
tumor cells by chromosomal deletions (e.g., monosomy 7) or copy number neutral
loss of heterozygosity (CN-LOH). Our data confirm that adult and pediatric MDS
are separate diseases with disparate mechanisms, and that SAMD9/SAMD9L mutations
represent a new class of MDS predisposition.
