Familial Mediterranean fever in Syrian children: phenotype-genotype correlation.

[familial mediterranean fever]

Familial Mediterranean fever (FMF ) is an autosomal recessive disease characterized by recurrent attacks of serosal membranes . In this study , 103 unrelated Syrian children were included . Mutation screening of the MEditerranean FeVer gene was performed for 12 mutations . Abdominal pain was observed in 91 (88 .3 Â %) of the patients , fever in 82 (79 .6 Â %), arthritis in 27 (26 .2 Â %), pleuritis in 7 (6 .7 .5 Â %), rash and erysipelas -like erythema in 5 (4 .8 Â %), myalgia in 5 (4 .8 Â %), headache in 5 (4 .8 Â %) and Henoch-Schonlein purpura in 1 (0 .97 Â %). The most frequent mutation was M 694 V . In order to determine the association between M 694 V and clinical features of FMF , we compared the disease features between patients with and without this mutation . The presence of M 694 V was found to be associated with more severe course of FMF , earlier age of onset and more frequent arthritis in the Syrian children with FMF compared to other FMF patients who do not have this mutation .
