Zusammenfassung

Schwere kongenitale Lipodystrophie, progeroide Fazies und variable Symptome eines Marfan-Syndroms stellen eine eigene Entität dar, nämlich eine Sonderform des Marfan-Syndroms mit einer trunkierenden Mutation am 3’-Ende des Fibrillin-1-Gens im vorletzten und letzten kodierenden Exon. Das mutierte Protein entgeht hochwahrscheinlich dem „nonsense mediated decay“ (NMD) und ruft dadurch offenbar diesen speziellen Phänotyp hervor. Es sind bislang erst 5 Fälle mit diesem Krankheitsbild publiziert worden; bei 3 dieser Patienten wurde das Krankheitsbild bisher molekulargenetisch bestätigt. Bei folgenden klinischen Zeichen sollte diese Diagnose berücksichtigt und abgeklärt werden: intrauterine Wachstumsretardierung, progeroide Fazies schon bei Geburt, vermindertes subkutanes Fettgewebe und variable Zeichen eines Marfan-Syndroms.

Abstract

Severe congenital lipodystrophy, progeroid facies and additional variable features of Marfan syndrome represent a unique entity: a Marfan syndrome variant caused by a truncating mutation at the 3’ end of the fibrillin 1 gene in the penultimate and final coding exons. It is highly likely that the mutant protein avoids nonsense mediated decay (NMD) and thus gives rise to this special phenotype. Only five cases of this pattern of symptoms have been published to date; in three instances the diagnosis was confirmed by molecular genetics. The following clinical features require that this diagnosis be considered and clarified: retarded intrauterine growth, progeroid facies at birth, reduced levels of subcutaneous fat and other variable features of Marfan syndrome.
