Loss of Fnip1 alters kidney developmental transcriptional program and synergizes with TSC1 loss to promote mTORC1 activation and renal cyst formation.

PLoS One 2018 13;13(6):e0197973. Epub 2018 Jun 13.

The Department of Comparative Medicine, University of Washington, Seattle, Washington, United States of America.

Birt-Hogg-Dube' Syndrome (BHDS) is a rare genetic disorder in humans characterized by skin hamartomas, lung cysts, pneumothorax, and increased risk of renal tumors. BHDS is caused by mutations in the BHD gene, which encodes for Folliculin, a cytoplasmic adapter protein that binds to Folliculin interacting proteins-1 and -2 (Fnip1, Fnip2) as well as the master energy sensor AMP kinase (AMPK). Whereas kidney-specific deletion of the Bhd gene in mice is known to result in polycystic kidney disease (PKD) and renal cell carcinoma, the roles of Fnip1 in renal cell development and function are unclear.

Morphological clues to the appropriate recognition of hereditary renal neoplasms.

Semin Diagn Pathol 2018 May 14;35(3):184-192. Epub 2018 Feb 14.

Department of Pathology and Laboratory Medicine, University of Tennessee Health Sciences, Memphis, USA; Department of Urology, University of Tennessee Health Sciences, Memphis, USA.

An important emerging role of the surgical pathologist besides the traditional tasks of establishment of the diagnosis and documentation of prognostic and predictive factors, is to recognize the possibility of a hereditary condition in cases where the histology is suggestive for a familial cancer syndrome. In recent years, the knowledge regarding all of the above roles, including the role of recognition of familial cancer, has particularly expanded in renal neoplasms with the close scrutiny to morphology, molecular correlates and clinical features of the different sub-types of renal cell carcinoma. Awareness of these clinically distinctive sub-types and their associated histologic clues will prompt the pathologist for further immunohistochemical or molecular work up, to look for clinical information to support the suspected diagnosis of familial cancer, to alert managing physician/s to look for stigmata of history of familial cancer, which will permit triaging patients and their families for appropriate genetic counseling.

[Birt-Hogg-Dubé syndrome is a rare but important cause of pneumothorax].

Ugeskr Laeger 2018 01;180(5)

Birt-Hogg-Dubé syndrome (BHD) is an autosomal-dominant genodermatosis manifesting as a multisystemic disorder. The most common presentation of pulmonary involvement is spontaneous pneumothorax, and it has recently been estimated, that up to 5-10% of patients with primary spontaneous pneumothorax have underlying BHD. The purpose of this case report is to stress the paramount importance of a thorough family history in patients with spontaneous pneumothorax and to recommend, that patients with a spontaneous pneumothorax and a personal or family history of pneumothorax should be screened for BHD.

Hereditary kidney cancer syndromes: Genetic disorders driven by alterations in metabolism and epigenome regulation.

Cancer Sci 2018 Mar 15;109(3):581-586. Epub 2018 Feb 15.

Department of Urology, Yokohama City University, Yokohama, Japan.

Although hereditary kidney cancer syndrome accounts for approximately five percent of all kidney cancers, the mechanistic insight into tumor development in these rare conditions has provided the foundation for the development of molecular targeting agents currently used for sporadic kidney cancer. In the late 1980s, the comprehensive study for hereditary kidney cancer syndrome was launched in the National Cancer Institute, USA and the first kidney cancer-associated gene, VHL, was identified through kindred analysis of von Hippel-Lindau (VHL) syndrome in 1993. Subsequent molecular studies on VHL function have elucidated that the VHL protein is a component of E3 ubiquitin ligase complex for hypoxia-inducible factor (HIF), which provided the basis for the development of tyrosine kinase inhibitors targeting the HIF-VEGF/PDGF pathway.

Difference of the progression of pulmonary cysts assessed by computed tomography among COPD, lymphangioleiomyomatosis, and Birt-Hogg-Dubé syndrome.

PLoS One 2017 8;12(12):e0188771. Epub 2017 Dec 8.

Divisions of Respiratory Medicine, Juntendo University Faculty of Medicine & Graduate School of Medicine, Bunkyo-Ku, Tokyo, Japan.

Many groups developed the methods to quantitatively analyze low attenuation area (LAA) on chest CT in patients with cystic lung diseases. Especially in COPD, it was reported that the cumulative size distribution of LAA clusters follows a power law characterized by the exponent D, which reflect the fractal dimension of terminal airspace geometry. We hypoyhesized that the quantitative charateristics of LAA clusters including fractal property might indicate the different features of the progression of cysts in cystic lung diseases. Read More

FLCN: The causative gene for Birt-Hogg-Dubé syndrome.

Gene 2018 Jan 29;640:28-42. Epub 2017 Sep 29.

Urologic Oncology Branch, Center for Cancer Research, National Cancer Institute, Bethesda, MD 20892, United States. Electronic address:

Germline mutations in the novel tumor suppressor gene FLCN are responsible for the autosomal dominant inherited disorder Birt-Hogg-Dubé (BHD) syndrome that predisposes to fibrofolliculomas, lung cysts and spontaneous pneumothorax, and an increased risk for developing kidney tumors. Although the encoded protein, folliculin (FLCN), has no sequence homology to known functional domains, x-ray crystallographic studies have shown that the C-terminus of FLCN has structural similarity to DENN (differentially expressed in normal cells and neoplasia) domain proteins that act as guanine nucleotide exchange factors (GEFs) for small Rab GTPases. FLCN forms a complex with folliculin interacting proteins 1 and 2 (FNIP1, FNIP2) and with 5' AMP-activated protein kinase (AMPK). Read More

Am J Clin Dermatol 2018 Feb;19(1):87-101

Department of Dermatology, University of California San Diego, 8899 University Center Lane, Suite 350, San Diego, CA, 92122, USA.

Birt-Hogg-Dubé syndrome (BHD) is an autosomal dominant genodermatosis with malignant potential characterized by cutaneous and extracutaneous stigmata. Aberrations in the folliculin (FLCN) gene, which is located on chromosome 17, have been discovered in individuals with this condition. Over 150 unique mutations have been identified in BHD.

Lung ultrasound has limited diagnostic value in rare cystic lung diseases: a cross-sectional study.

Eur Clin Respir J 2017 1;4(1):1330111. Epub 2017 Jan 1.

Department of Respiratory Medicine, Odense University Hospital, Odense C, Denmark.

: Lung ultrasound (LUS) used to identify interstitial syndrome (IS) and pleural thickening related to diffuse parenchymal lung disease (DPLD) has shown significant correlations with ground glass opacity (GGO) on high-resolution computed tomography (HRCT). However, the applicability of LUS in patients with DPLD subtypes as rare cystic lung diseases has not previously been investigated. This study aimed to observe if distinctive LUS findings could be found in patients with lymphangioleiomyomatosis (LAM), pulmonary Langerhans cell histiocytosis (PLCH), and Birt-Hogg-Dubé syndrome (BHDS).

Birt-Hogg-Dube (BHD) disease is an autosomal dominant cancer syndrome characterized by benign skin tumors, renal cancer and spontaneous pneumothorax and is caused by mutations in the Folliculin (FLCN) gene. Benign skin tumors and pneumothorax occur in the majority of patients affected by BHD syndrome, but only 30-45% of them develop renal cell carcinoma (RCC) with a median age of diagnosis at 48. The earliest onset of RCC in a BHD patient has been reported at age 20. Read More

Purpose Of Review: Diffuse cystic lung diseases (DCLDs) are a heterogeneous group of disorders with varying pathophysiologic mechanisms that are characterized by the presence of air-filled lung cysts. These cysts are prone to rupture, leading to the development of recurrent spontaneous pneumothoraces. In this article, we review the epidemiology, clinical features, and management DCLD-associated spontaneous pneumothorax, with a focus on lymphangioleiomyomatosis, Birt-Hogg-Dubé syndrome, and pulmonary Langerhans cell histiocytosis.
