Somatic DICER1-Mutant Benign Thyroid Nodules in Adults: A Group of Follicular Nodular Disease With Continuous Growth.

Background: Germline DICER1 mutations cause familial multinodular goiter (MNG). However, the prevalence of somatic DICER1 mutations in non-MNG benign thyroid nodules and their characteristics remain unknown.

Methods: Adult-onset thyroid nodules with a pathological diagnosis were genotyped via targeted sequencing.
