DiseaseAssertion: MPS-H

FamilyInfo: Mother and father received parental testing.

CasePresentingHPOs: Joint stiffness (HP:0001387)

CaseHPOFreeText: She had a tendency to fall without normal protective reactions. Typical facial appearance and other clinical findings were suggestive of MPS I Hurler, and this diagnosis was also supported by X-ray images which showed characteristic skeletal changes. Motor development appeared slightly delayed, while intellectual development was considered to be normal.

CaseNotHPOs: Corneal clouding (HP:0007957)

CaseNotHPOFreeText: N/A

CaseEnzymeAssay: 0.006 μmol phenol/18 h/mg protein. Normal range of IDUA activity (n = 52, healthy volunteers): 0.143–0.351 μmol phenol/18 h/mg protein.

CaseUrineGAGs: Urinary GAG excretion - 101 mg GAG/mmol creatinine. The patient demonstrated increased excretion of GAGs, which were identified as HS and DS. Normal age adjusted range of urinary GAG excretion: 14–34 mg GAG/mmol creatinine.

CaseERT: The patient was initiated on enzyme replacement therapy (ERT) with weekly infusions of recombinant α-l-iduronidase 100 IE/kg

CaseBMT: The patient successfully received hematopoietic stem cell transplantation (HSCT) 4 months after ERT.
