FLCN

MIM.607273 17p11.2

Saturday 27 November 2004

The folliculin gene (FLCN), also known as BHD, is the only known susceptibility gene for Birt-Hogg-Dubé syndrome.

Birt-Hogg-Dubé syndrome is a rare inherited cancer syndrome caused by a germline mutation in the folliculin (FLCN) gene, but the genetic causes for histologic diversity of renal tumors in Birt-Hogg-Dubé syndrome have not been elucidated.

Multiple renal tumors of diverse morphology are rare and typically seen in Birt-Hogg-Dubé syndrome.

Pathology

BHDS is the autosomal dominant predisposition to the development of follicular hamartomas, lung cysts, spontaneous pneumothorax, and/or kidney neoplasms.

To date, 53 unique germline mutations have been reported. FLCN mutation detection rate is 88%. FLCN encodes a predicted 579-amino acid protein, designated folliculin that is highly conserved between humans and homologs in mice, Drosophila, and C. elegans.
