Genotype-phenotype assessment of common genotypes among patients with familial Mediterranean fever
Abstract
Objective: To study genotype-phenotype correlation for the 4 most common genotypes found among patients with familial Mediterranean fever (FMF).
Methods: Thirty patients with the M694V/M694V genotype, 32 with M694V/V726A genotype, 25 with M694V/E 148Q genotype, and 21 with V726A/V726A genotype were assessed for various clinical manifestations of FMF, and overall disease severity.
Results: Patients with the M694V/M694V genotype were found to have an earlier age of onset, higher frequency of joint involvement, higher frequency of erysipelas-like erythema, and required higher doses of colchicine to control the disease compared to the other 3 genotypes.
Conclusion: The M694V/M694V genotype is associated with more severe disease compared to other common genotypes in patients with FMF.
