Evidence was seen for pleiotropic relationships, notably correlations for chronic lymphocytic leukemia with elevated familial
risk of other B cell tumors and myeloproliferative neoplasms.
Mediterranean fever is the result of mutations in the MEFV gene encoding pyrin that is a regulatory component of the intracellular inflammasome complex required for the conversion of pro-interleukin (IL)-1[beta] into active IL-1[beta].
Genetic analysis for the familial
Mediterranean fever gene (MEFV) revealed a homozygote mutation for M694V.
The majority of the cases reported were from Europe, specifically Italy, Spain, and Germany., Although familial
aggregation is robust in FFI, nine sporadic cases have been reported. It is speculated that the annual incidence of FFI worldwide is about one out of a million people. There are no gender differences among FFI patients.

In some rare cases, familial
hypertension is caused by mutations within single genes.
Histological examination of liver biopsy specimens suggested progressive familial
