Three subjects were surprisingly found to carry genetic alterations associated with well-established genetic syndromes not usually related to desmoid tumors: two Lynch syndrome patients carried MSH6 mutation and VUS in MSH2 and one patient had a mutation in PALB2, which encodes a BRCA2 interacting protein that increases susceptibility to breast and pancreatic cancers [40]. The gene discussed is BRCA2; the disease is Lynch syndrome.
