Comment on list classification: Multiple studies have been published showing germline POT1 variants predispose to a broad spectrum of haematological cancers including chronic lymphocytic leukaemia, lymphomas and myeloid malignancies. Inclusion on this panel may be warranted to allow clinical surveillance of high-risk families.

However, haematologic malignancies often occur as part of a broader spectrum of POT1-associated cancers and therefore this gene will be flagged for additional GMS expert review to determine whether it is appropriate to include on this panel.

Panel Version: 4.32
Germline variants in POT1 have been linked to a wide range of haematological malignancies including myeloid and lymphoid neoplasms (PMID: 27528712; 29693246; 33216348; 34193977; 34769003) and multiple myeloma (PMID: 36467798; 39845416). POT1 variants lead to telomeric elongation and increased telomere fragility as the main functional effect.
