Hereditary Renal Cancer Syndromes: Clinicopathologic Features and Correlation With Tumors Harboring Somatic Mutations.

Abstract

Hereditary renal cancer syndromes account for approximately 5% to 8% of all renal cell carcinomas (RCCs) and are caused by germline alterations, mainly in tumor suppressor genes. Advances in molecular testing have led to the identification of new hereditary syndromes and expanded our understanding of the genetic landscape of renal neoplasia. This review summarizes both well-established and recently described hereditary renal cancer syndromes, highlighting their clinical, pathologic, and molecular features. Emphases are placed on genotype-phenotype correlations and the relationship between germline and somatic alterations in tumors. Understanding these correlations is critical for diagnosis, risk assessment, surveillance, and management and underscores the importance of a high index of clinical suspicion for early detection to optimize patient outcomes.
