Inherited risk factors for myeloproliferative neoplasms

Unveiling the Germline Predisposition to Myeloproliferative Neoplasms

Fondazione IRCCS Policlinico San Matteo di Pavia · NCT07204392

This project will test whether inherited (germline) genetic changes raise the risk of myeloproliferative neoplasms in people diagnosed before age 27 or with multiple affected relatives.

What this trial studies

This observational study at Fondazione IRCCS Policlinico San Matteo will collect germline DNA from patients with classical Ph-negative MPNs (PV, ET, prePMF, overt PMF, MPN-U) who were diagnosed under age 27 or who have at least one other first- or second-degree relative with a hematologic malignancy. Participants must have prior characterization of their somatic driver mutation (JAK2, CALR, MPL). Researchers will perform germline genetic analyses, including sequencing and comparison with population databases, to identify variants that predispose to MPN. No treatments are given as part of the protocol; results aim to clarify inherited risk and inform future genetic counseling and screening strategies.

Who should consider this trial

Good fit: People with PV, ET, prePMF, overt PMF, or MPN-U who were diagnosed before age 27 or who have at least one first- or second-degree relative with a hematologic malignancy, and who have prior somatic driver mutation testing, are ideal candidates.

Not a fit: Patients without the early-age diagnosis or relevant family history, or those unwilling to provide germline samples, are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the work could identify inherited genetic markers that help predict who is at higher risk, enabling earlier monitoring and targeted genetic counseling.

How similar studies have performed: Previous work has documented common polymorphisms and familial clustering that suggest inherited risk, but comprehensive germline sequencing in selected MPN families is still relatively novel.
