Ill just have to stay one step ahead of it, he says. No significant difference has been found in the symptoms experienced by families with an insertion at that location compared to those who have a deletion, but mutations in FLCN associated with BHD syndrome are heterogeneous, and are often nonsense mutations or frameshift mutations that cause early truncation of the protein product at the carboxy terminus. Policy. Hereditary bilateral, multifocal kidney tumors similar to those seen in BHD can occur with von HippelLindau disease (clear cell renal cell carcinoma), hereditary papillary renal cancer (papillary renal cell carcinoma), and hereditary leiomyomatosis and renal cell cancer syndrome.

BHD-associated tumorigenesis differs between the kidney, where loss of FLCN heterozygosity is responsible for cancers, and the skin, where FLCN is strongly expressed in heterozygotes. Heterozygotes have renal abnormalities seen very early in life that develop into clear-cell and hybrid tumors, significantly shortening the animals' lifespans; they also are prone to endometrial and salivary gland clear-cell hyperplasia as well as rhabdomyolysis.
