BHD Research

Last week Findacure hosted a webinar explaining the complex medical research field that introduced the different stages of pre-clinical and clinical research necessary to get a treatment available to patients. The first talk focused on pre-clinical research and was presented by Oliver Timmis from the AKU Society, a charity that supports patients with the rare … Read more

Obesity is often associated with decreases in the proportion of skeletal muscle slow-twitch fibers and insulin sensitivity. Slow-twitch fibers are rich in mitochondria and utilize fatty acid oxidative phosphorylation for energy production. In their new study, Zhou et al. (2017) explore the role of the FLCN/FNIP1/AMPK signalling pathway in obesity-induced reductions in slow-twitch fibers and … Read more

The gene FLCN is inactivated in individuals with BHD syndrome. The FLCN gene encodes the protein Folliculin, which is a putative tumour suppressor. Over 150 different FLCN mutations have been identified, most of which are likely to be pathogenic (LOVD-hosted FLCN mutation database). The majority of these mutations are frameshift, nonsense, insertion/deletion, or splice site mutations, resulting in truncation and inactivation … Read more

Birt-Hogg-Dubé syndrome (BHD), also known as Hornstein–Knickenberg syndrome is an inherited disease associated with skin lesions, lung cysts, pneumothorax and kidney cancer. Jensen et al. (2017) present a new case report of BHD and a review of the literature. This is a great opportunity to review the genetics, clinical manifestations, diagnosis, treatment, prognosis and follow-up … Read more

mTORC1 and mTORC2 are two distinct mammalian TOR (target of rapamycin) complexes that regulate cell growth and metabolism. In cancer, genetic alterations lead to activation of mTOR signalling impacting tumour metabolism. Upregulated glutaminolysis is part of the metabolic reaction occurring in cancer that liberates high levels of ammonium, a toxic waste product. Although the importance … Read more

In the field of rare diseases one of the key points of progress is to ensure that rare disease patients benefit from advances in medical sciences. To promote this, the global biotechnology company Shire hosted a Rare Disease Summit yesterday in London, which focused on the policy environment for patient access to orphan drugs and … Read more

Previous studies show that BHD syndrome causes spontaneous pneumothorax (SP) in 24-38% of patients, with a recurrence rate of up to 75% (Toro et al., 2007; Toro et al., 2008; Houweling et al., 2011). A common preventative strategy used following an initial SP in patients with BHD is pleurodesis, however, its efficacy in preventing recurrent … Read more

As mentioned in last week’s blog, the 3rd International Rare Disease Research Consortium (IRDiRC) conference was held on the 8-9th February in Paris bringing together international experts in the rare disease field to discuss progress and to set new goals. One of the sessions of the conference focused on global trends in patient advocacy in the rare … Read more

The 3rd International Rare Disease Research Consortium (IRDiRC) conference was held last week in Paris. It brought together international experts in the fields of public health, funding agencies, academic research, patient advocacy and health industry to discuss the progress in the rare disease field and to set new goals for the next decade. The conference … Read more

To date, there have been no prospective studies attempting to diagnose BHD syndrome or literature reviews on BHD in Korea. Park et al. (2017) address this in their new study that aims to detect BHD prospectively in patients undergoing chest computed tomography (CT) scans and to classify the characteristics of BHD in Korea. The authors … Read more
