Samenvatting

Doel. Het beschrijven van de klinische en moleculair-genetische karakteristieken van patiëntn met het Bloom-syndroom (BS ) in Nederland in vergelijking met het internationale cohort BS-patiënten van de Bloom’s Syndrome Registry (BSR).

Patiënten. Voor deze studie werd contact gezocht met alle klinisch genetische centra in Nederland, waardoor 15 patiënten met BS werden geëdentificeerd. Van deze patiënten werden klinische en moleculair-genetische gegevens verzameld en vergeleken met de publiekelijk beschikbare data van de 256 patiënten uit de BSR.

Conclusie. We concluderen dat de prevalentie van maligniteiten en niet-insulineafhankelijke diabetes mellitus bij BS-patiënten in Nederland wat lijkt te verschillen ten opzichte van het BSR-co-hort. We beschrijven een maligniteit (rabdomyosarcoom) die niet eerder beschreven werd bij patiëntn met BS en rapporteren twee niet eerder beschreven mutaties.

Summary

Aim. To describe the clinical and molecular genetic characteristics of Bloom syndrome (BS) patients in the Netherlands, in comparison with the international Bloom syndrome cohort as described in the Bloom’s Syndrome Registry (BSR).

Patients. For this study, all clinical genetic departments in the Netherlands were contacted, which identified 15 patients with Bloom syndrome. Of these patients, clinical and molecular genetic data were gathered and compared with the public available data of the BSR.

Conclusions. We conclude that the prevalence of malignancies and non-insulin dependent diabetes mellitus in BS patients in the Netherlands seems to differ from patients from the BSR.We describe a malignancy (rhabdomyosarcoma) which has not previously been reported in relation to BS and report on two mutations that have not yet been described.
