Zusammenfassung
Bei einem 4-jährigen Mädchen konnte die Diagnose Osteogenesis imperfecta Typ I anhand folgender klinischer Merkmale gestellt werden: 4 Frakturen jeweils nach Bagatelltraumata, intensiv blaue Skleren beidseits, Zahnschmelzanomalien, Makrozephalie mit vorgewölbter Stirn. Die Diagnose wurde molekulargenetisch bestätigt. Dabei fand sich eine heterozygote Punkt-mutation Arg420Stop im COL1A1-Gen, welche in der Literatur bisher nicht beschrieben ist.
Abstract
In a 4 year old girl the diagnosis osteogenesis imperfecta type I was suspected by following clinical criteria: four fractures after small trauma, intensive blue sclera, anomalies of dental enamel, macrocephalie with frontal bassing. Clinical diagnosis could be verified by moleculargenetic analysis, a newly recognized heterozygous point mutation (Arg420Stop) in the COL1A1-gene was found.
