Germline Alterations in RASAL1 in Cowden Syndrome Patients Presenting with Follicular Thyroid Cancer and in Individuals with Apparently Sporadic Epithelial Thyroid Cancer

摘要

Context:RASAL1 has recently been identified as an important tumor suppressor for sporadic thyroid tumorigenesis, particularly for follicular thyroid cancer (FTC) and anaplastic thyroid cancer. Thyroid cancer is an important component of Cowden syndrome (CS). Patients with germline PTEN mutations have an overrepresentation of FTC over other histological subtypes.
