Zusammenfassung

Das α-Thalassämie-Retardierungs-Syndrom (ATRX-Syndrom, MIM#301040) führt bei Jungen zu schwerer mentaler Retardierung, Muskelhypotonie, fazialer Dysmorphie und Genitalfehlbildungen. Wir berichten über eine Familie mit 2 betroffenen Knaben. Die Diagnose gelang mittels materner X-Inaktivierungsanalyse und molekulargenetischer Analyse des ATRX-Gens bei dem Sohn, wobei sich eine bislang noch nicht beschriebene Mutation in Exon 34 fand.

Abstract

Alpha-thalassemia X-linked mental retardation (ATRX, MIM#301040) syndrome is associated with severe mental retardation, muscular hypotonia, facial dysmorphism, and genital anomalies in males. We present the case of a family with two affected boys. The diagnosis was made by maternal X-chromosome inactivation studies which showed marked skewing of maternal X-chromosome inactivation and ATRX analysis revealed a novel mutation in exon 34.
