Gene References into Functions
  1. Two FLCN mutations have been identified in Birt-Hogg-Dube syndrome patients: One is an insertion mutation previously reported in three Asian families; while the other is the first mutation (originally found in Asian populations) that has ever been detected in a French family. PMID: 29357828
  2. FLCN gene analysis revealed a heterozygous FLCN{NM_144997.5}:c.1285dupC mutation in all affected members. The clinical features of BHD syndrome are heterogeneous with wide intra-familial and interfamilial variation. It is caused by mutations of the FLCN gene. PMID: 28775225
  3. The molecular insight into the folliculin dynamics in the presence and absence of mutations may provide valuable information regarding the interactions essential for normal functioning of cellular process and the molecular basis of Birt-Hogg-Dube syndrome PMID: 27484154
  4. The present identification of two mutations not only further supports the important role of tumor suppressor FLCN in Birt-Hogg-Dube syndrome and primary spontaneous pneumothorax, but also expands the spectrum of FLCN mutations. PMID: 28785590
  5. In the folliculin gene, a similar genotype spectrum but different mutant loci was determined in Chinese patients with Birt-Hogg-Dube syndrome compared with European and American patients. PMID: 28558743

  7. Seventy-six of 156 FLCN mutation carriers (120 probands and 36 sibs, 48.7%) had skin papules; however, cutaneous manifestations were so subtle that only one patient voluntarily consulted dermatologists. Japanese Asian BHD families have three FLCN mutational hotspots. PMID: 27220747
  8. A nonsense mutation of FLCN was found in a spontaneous pneumothorax family. The results expand the mutational spectrum of FLCN in patients with Birt-Hogg-Dube syndrome. PMID: 27486260

  10. We report Smith-Magenis syndrome who presents bilateral renal tumors. This is most likely related to haploinsufficiency of FLCN gene, located in the deleted region PMID: 27633572
  11. For patients whose clinical features are atypical, detection of germline mutation in FLCN gene would help confirm diagnosis. The 2 mutations we reported would expand the mutation spectrum of FLCN gene associated with BHD syndrome PMID: 27258496
  12. DNA sequence analyses determined that there was a two base pair deletion in exon 4 of the FLCN gene, confirming the diagnosis of BHD syndrome. PMID: 27780965
  13. We identified a hitherto unreported pathogenic FLCN frameshift deletion c.563delT (p.Phe188Serfs*35) in a family of a 46-year-old woman presented with macrohematuria due to bilateral chromophobe renal carcinomas PMID: 26342594
  14. FLCN irregulation in lung cysts of primary spontaneous pneumothorax is not associated with promoter methylation. PMID: 26398834
  15. mTOR inhibitor, sirolimus, suppresses the tumor's growth, suggesting that mTOR inhibitors might be effective in control of FLCN-deficient RCC. PMID: 26418749
  16. we show that glycogen accumulates in kidneys from mice lacking FLCN and in renal tumors from a BHD patient PMID: 26439621
  17. Case Report: FLCN deletion mutation in members of Indian Birt-Hogg-Dube syndrome family. PMID: 25827758
  18. This report documents the first identification of founder mutations in FLCN, as well as expands mutation spectrum of the gene PMID: 25807935
  19. FLCN-related renal cell carcinomas showed overexpression of GPNMB and underexpression of FLCN, whereas sporadic tumors showed inverted patterns. PMID: 25594584
  20. The FLCN-GABARAP association is modulated by the presence of either folliculin-interacting protein (FNIP)-1 or FNIP2 and further regulated by ULK1. PMID: 25126726
  21. Two predominant genes, ephrin type A receptor 6 (EPHA6) and folliculin (FLCN), with mutations exclusive to African American CRCs, are by genetic and biological criteria highly likely African American CRC driver genes. PMID: 25583493
  22. Findings suggest that folliculin deficient renal cell carcinoma cells are highly sensitive to irradiation due to increased autophagic cell death, unlike other types of renal cell carcinoma. PMID: 24434776
  23. A rare mutation of the folliculin gene was detected in the patient and family members with Birt-Hogg-Dube syndrome with pulmonary cysts or pneumothorax, but no skin or renal lesions. PMID: 24346394
  24. Birt-Hogg-Dube (BHD) syndrome is a recently discovered autosomal-dominant disease caused by a mutation in the folliculin gene. PMID: 24996715
  25. loss of FLCN constitutively activates AMPK, resulting in PGC-1alpha-mediated mitochondrial biogenesis and increased ROS production PMID: 24762438
  26. FLCN germ-line mutation is associated with spontaneous pneumothorax and renal cancer PMID: 23264078
  27. Results suggest that Birt-Hogg-Dube (BHD)syndrome-causing FLCN mutants may retain partial functionality. Thus, several BHD symptoms may be due to abnormal levels of FLCN rather than its complete loss. PMID: 23784378
  28. Tumor suppression function of FLCN may be linked to its impact on the cell cycle. PMID: 23874397
  29. FLCN localizes to motile and non-motile cilia, centrosomes and the mitotic spindle. Alteration of FLCN levels can cause changes to the onset of ciliogenesis. In three-dimensional culture, abnormal expression of FLCN disrupts polarized growth of kidney cells and deregulates canonical Wnt signalling. Findings suggest that BHD is a ciliopathy, with symptoms at least partly due to abnormal ciliogenesis. PMID: 23784378
  30. Birt-Hogg-Dube syndrome in a patient with melanoma and a novel mutation in the FCLN gene. PMID: 23414156
  31. FLCN functions as a tumor suppressor by negatively regulating rRNA synthesis. PMID: 23077212
  32. Germline mutation analysis of the FCLN gene in mother and daughter cases with renal cell neoplasms showed a deletion of 18 bp in exon 5(c.332_349del/p.H111_Q116del), predicting an alteration of the amino acid sequence of "HPSHPQ" replaced by a single amino acid, "L". PMID: 22211584
  33. Findings suggest that aspects of folliculin tumour suppressor function are linked to interaction with p0071 and the regulation of RhoA signalling. PMID: 22965878
  34. These data support a model in which dysregulation of the FLCN-p0071 interaction leads to alterations in cell adhesion, cell polarity, and RhoA signaling. PMID: 23139756
  35. These findings identify novel pathways and targets linked to folliculin tumour suppressor activity. PMID: 23155228
  36. FLCN deficiency and subsequent increased PPARGC1A expression result in increased mitochondrial function and oxidative metabolism as the source of cellular energy, which may drive hyperplastic transformation. PMID: 23150719
  37. Study reports a novel in-frame deletion mutation p.F143del (c.427_429delTTC) in exon 6 of FLCN gene in a Korean proband and her two sisters. PMID: 22446046
