Investigation of different genomic variants in familial Mediterranean fever cases with monoallelic MEFV mutation.

This study is one of the most extensive aetiological researches in FMF cases with monoallelic MEFV mutation. We have shown that genotype-phenotype correlation in these cases may not be established by rare genetic variants and discussed underlying causes. Clinical criteria with emphasis on colchicine response and family history should be the main tool and genetic results should only be used for support in FMF diagnosis.
