Background: PNPK gene mutations result in DNA repair disorders and have a spectrum of neurodevelopmental manifestations. To date, cancer predisposition has not been described in patients with PNKP mutations.
Observation: Here, we report a patient with PNKP mutation, who developed AML at age of five and underwent reduced-intensity HSCT.
Conclusion: Although many DNA repair disorders are known to have increased risk of malignancy, association between PNKP mutations and malignancy is not well-described. This report is the first description of a PNPK mutation patient developing a malignancy and undergoing curative HSCT.
Keywords: AML; DNA repair disorders; HSCT; PNKP mutation.
