Germline compound heterozygous poly-glutamine deletion in USF3 may be involved in predisposition to heritable and sporadic epithelial thyroid carcinoma.

ABSTRACT: Cowden syndrome (CS) is an autosomal dominant disorder that predisposes to breast, thyroid, and other epithelial cancers. Differentiated thyroid carcinoma (DTC), as one of the major component cancers of CS, is the fastest rising incident cancer in the USA, and the most familial of all solid tumours. To identify additional candidate genes of CS and potentially DTC, we analysed a multi-generation CS-like family with papillary thyroid cancer (PTC), applying a combined linkage-based and whole-genome sequencing strategy and identified an in-frame germline compound heterozygous deletion, p.[Gln1478del];[Gln1476-Gln1478del] in USF3 (previously known as KIAA2018). Among 90 unrelated CS/CS-like individuals, 29% were found to have p.[Gln1478del];[Gln1476-Gln1478del]. Of 497 TCGA PTC individuals, 138
