Case#: Patient F (female), diagnosed at 4 years and 6 months on the basis of clinical findings, an elevated urinary glycosaminoglycan level, and low α-l-iduronidase activity in leukocytes. Patient F was 104.0 cm tall (75th percentile).

DiseaseAssertion: MPS1-H/S

FamilyInfo: The patient is an older sibling who was diagnosed with the disease and has an affected younger brother.

CasePresentingHPOs: Coarse facial features, joint stiffness, thick skin, corneal clouding, hepatosplenomegaly, dysostosis multiplex (HP:0000280, HP:0001387, HP:0001072, HP:0007957, HP:0001433, HP:0000943)

CaseHPOFreeText: Moderate mitral insufficiency with thickened valve leaflets and anterior edge prolapse; mild left atrium thickening and increased pulmonary pressure were also present. Radiographic skeletal examination showed several signs of hip hypoplasia, ovoid shape of lumbar vertebral bodies, V-shaped distal ulnar and radial extremities, and short and broad metacarpal bones. Although she had normal intelligence, she developed obstructive hydrocephalus, which required shunting at 7 months of age.

CaseEnzymeAssay: Low α-l-iduronidase activity in leukocytes

CaseUrineGAGs: Elevated urinary glycosaminoglycan levels

CaseERT: Yes - Patient F started laronidase at 5 years of age, also at the standard dose. After 5 years of therapy, she was 138.0 cm tall (90th percentile), her liver and spleen volume had normalized, her skin had become less thickened, and her shoulder flexion and extension were moderately improved. Her dysostosis multiplex, cardiac function, and corneal clouding (visual acuity: 10/10) had stabilized but were not improved.
