Among the patients with UBA1 variants of unknown origin or putative germline, Graves’ disease with recurrent thyroid nodules development after goiter operation was documented for one MDS patient (L568V) and there were two additional patients with thyroid involvement (hypothyroidism, R784Q, CLL; intrathyroidal parathyroid carcinoma, N139K, MDS). This evidence concerns the gene UBA1 and thyroid nodule.
