Mucopolysaccharidosis type VII as a cause of recurrent non-immune hydrops fetalis.
キーワード
概要
BACKGROUND
Mucopolysaccharidosis type VII (MPS VII) is a rare lysosomal storage disease first described by Sly in 1973. There are fewer than thirty reported cases world wide. This extremely rare disorder can present in-utero as hydrops fetalis and has a high recurrence rate. However, prenatal diagnosis in the absence of a previously affected child, has not been reported to date.
METHODS
This is a case of a non-consanguineous couple, with no history of a previously affected child with MPS VII, presenting with recurrent hydrops fetalis. During the work-up, the affected fetus was diagnosed in-utero with beta-glucuronidase deficiency which is pathognomonic for MPS VII. Prenatal diagnosis was then performed in subsequent pregnancies.
CONCLUSIONS
The importance of an extensive and thorough investigation for the etiology of hydrops fetalis is discussed.
