Clinical, Pathological, and Molecular Studies of Two Families with Iodide Organification Defect.

abstract：:Recently, the immunohistochemistry (IHC) for N-RAS Q61R has been developed and commercialized for clinical practice. Here, we investigated the reliability of IHC to identify N-RAS Q61R mutated thyroid neoplasia. A series of 24 consecutive thyroid lesions undergone surgery following indeterminate cytology were enrolled...
