BHD causes pneumothoraces during childhood in rare cases

by Lizzie Perdeaux in BHD Research Blog

Birt-Hogg-Dubé Syndrome is caused by inactivating mutations in the FLCN gene, characterised by skin lesions on the face and upper body; lung cysts and predisposition to pneumothorax; and kidney cancer. Although symptoms typically appear in the third and fourth decade … Continue reading →... Read more »

Intratumoral peripheral small papillary tufts might be a diagnostic clue of BHD

by Lizzie Perdeaux in BHD Research Blog

Contrary to other hereditary kidney cancer conditions, BHD-associated renal tumours are known to be histologically diverse and discordant within families, meaning that members of the same family do not necessarily get the same type of kidney tumour (Pavlovich et al., … Continue reading →...

FNIP1 is required for iNKT cell maturation

by Lizzie Perdeaux in BHD Research Blog

In 2012, two independent studies found that the FLCN-interacting protein FNIP1 is required for proper β-cell maturation, and were the first studies to suggest a role for FLCN and its partners in the immune system. Following their 2012 discovery that … Continue reading →... Read more »

FLCN is necessary for the survival and function of Type II alveolar epithelial cells

by Lizzie Perdeaux in BHD Research Blog

Roughly 90% of BHD patients develop lung cysts, which are thought to also cause spontaneous pneumothorax in 1 in 4 BHD patients (Houweling et al., 2011, Predina et al., 2011). However, although lung cysts are a highly penetrant symptom of … Continue reading →... Read more »
