Hurler disease

Friday 23 October 2009

Digital case

- Case 202 (HPC:202) : Lung in Hurler disease

Definition: Deficiency of alpha-L-iduronidase (MPS1) can result in a wide range of phenotypic involvement with 3 major recognized clinical entities:
- Hurler disease (MPS1H)
- Scheie disease (MPS1S) (MIM.607016)
- Hurler-Scheie disease (MPS1H/S) syndromes.

Hurler and Scheie syndromes represent phenotypes at the severe and mild ends of the MPS I clinical spectrum, respectively, and the Hurler-Scheie syndrome is intermediate in phenotypic expression.

MPS1 is more frequent than MPS2 (Hunter syndrome) (MIM.309900), which has no corneal clouding and pursues a slower course.

Synospis

- cardiopulmonary anomalies
- pulmonary Hurler disease

  • progressive respiratory failure
  • severe pulmonary arterial hypertension
  • upper airway obstruction
