“…In other studies, the prevalence of M694V mutation was reported as 48%, 71.3% and 74.3%, respectively (Yilmaz et al 2001;Ertekin et al 2005;Inal et al 2008). Phenotype and genotype correlation in FMF has not been explained definitely, but an increased risk of amyloidosis among M694V homozygotes was reported (Paut et al 2000;Yilmaz et al 2003;Dusunsel et al 2008). A recent research showed that the homozygous for M694V and the compound heterozygous for M694V were associated with a severe clinical course of FMF (Inal et al 2008).…”

“…Recent Turkish FMF Study Group records (including both adults and children) document a 1.2:1 (male: female) ratio. 8 The most serious complication of disease is amyloidosis, caused by tissue deposition of serum amyloid A, most notably in kidneys that ultimately leads to end-stage renal failure. 9 The type of mutation has been suggested to establish the severity of the disease.…”

“…1 Two major studies from Turkey find no association between the development of amyloidosis and M694V homozygosis, but according to study of Düşünsel et al, M694V homozygote genotype clearly forms a predisposition to development of amyloidosis. 8 The associations of M694V homozygosis with a more severe form of the disease and with a higher frequency of amyloidosis is reported although genotype-phenotype correlation is not well established. Nevertheless, in several other studies, the association of M694V mutation seems not prevalent among FMF patients, especially in Turks.…”
