Acquired copy-neutral loss of heterozygosity of chromosome 1p as a molecular event associated with marrow fibrosis in MPL-mutated myeloproliferative neoplasms

Abstract
Key Points In MPL exon 10–mutated myeloproliferative neoplasms, the MPL-mutant allele burden varies considerably from about 1% to almost 100%. High mutation burdens originate from acquired copy-neutral loss of heterozygosity of chromosome 1p and are associated with marrow fibrosis.
