Living with 14q32 duplication syndrome

A rare chromosome condition that raises the chance of certain blood and bone marrow disorders in adulthood.

Understanding 14q32 duplication syndrome

14q32 duplication syndrome is a rare chromosome condition that raises the chance of certain blood disorders.

It is caused by an extra piece of the long arm of chromosome 14. It increases the chance of adult-onset blood and bone marrow disorders (myeloproliferative neoplasms), including acute myeloid leukemia and essential thrombocythemia. Some people may progress to myelofibrosis or secondary acute myeloid leukemia. GARD lists onset as adult.
