Article Abstract
Our understanding of how each hereditary kidney cancer adapts to its tissue microenvironment is incomplete. Here, we present single-cell transcriptomes of 108,342 cells from patient specimens including from six hereditary kidney cancers. The transcriptomes displayed distinct characteristics of the cell of origin and unique tissue microenvironment for each hereditary kidney cancer. Of note, hereditary leiomyomatosis and renal cell carcinoma (HLRCC)-associated kidney cancer retained some characteristics of proximal tubules, which were completely lost in lymph node metastases and present as an avascular tumor with suppressed T cells and TREM2-high macrophages, leading to immune tolerance. Birt-Hogg-Dubé (BHD)-associated kidney cancer exhibited transcriptomic intratumor heterogeneity (tITH) with increased characteristics of intercalated cells of the collecting duct and upregulation of FOXI1-driven genes, a critical transcription factor for collecting duct differentiation. These findings facilitate our understanding of how hereditary kidney cancers adapt to their tissue microenvironment.

Introduction: Sickle cell trait (SCT) is a hereditary condition that affects millions worldwide, predominantly in individuals of African, Mediterranean, and Middle Eastern descent. While traditionally considered a benign carrier state, emerging evidence suggests a potential association between SCT and malignancies. This study aims to evaluate the relationship between SCT and the risk of multiple myeloma, renal cancer, leukemia, hepatocellular carcinoma (HCC), and colorectal cancer.

Background: Immune complex-mediated membranoproliferative glomerulonephritis (IC-MPGN) and Alport syndrome are distinct glomerular diseases with different pathophysiologic mechanisms. Their coexistence is extremely rare and may present diagnostic and therapeutic challenges.
Case Presentation: A 42-year-old woman presented with persistent proteinuria and hematuria.

Background: Alport syndrome (AS) is a hereditary kidney disorder caused by pathogenic variations in COL4 genes and is clinically characterized by hematuria, proteinuria, and progressive renal impairment. IgA nephropathy (IgAN) is a clinicopathological syndrome characterized by the deposition of IgA or IgA-dominant in the glomerular mesangial areas.
Case Presentation: This article reports a case of a 2-year-and-3-month-old female toddler who presented with hematuria and proteinuria.

Background: Hereditary leiomyomatosis and renal cell carcinoma syndrome (HLRCC) is an autosomal dominant tumor predisposition syndrome with germline fumarate hydratase (FH) pathogenic variants. We describe the unusual clinical presentation, morphologic, and immunohistochemical features of bilateral renal cell carcinoma (RCC) occurring in polycystic kidneys in a 15-year-old male with HLRCC.
Case Presentation: The patient was diagnosed with bilateral polycystic kidneys at 1-year old.
