Case#: Patient 7, female, Han origin, 7 years old (age at diagnosis)

DiseaseAssertion: MPS1-H/S

FamilyInfo: N/A

CasePresentingHPOs: Global Developmental Delay, Macrocephaly, Joint stiffness, Hepatosplenomegaly (HP:0001263, HP:0000256, HP:0001387, HP:0001433)

CaseHPOFreeText: Cardiac disease

CaseNotHPOs: Mongolian macula, Hernia, Airway obstruction (HP:0011369, HP:0100790, HP:0006536)

CaseNotHPOFreeText: N/A

CaseEnzymeAssay: IDUA activity 0.3 nmol/h/mg protein. The normal range in Chinese controls was found to be 27.2–52 nmol/h/mg protein.

CaseUrineGAGs: Diagnosis was confirmed biochemically by the demonstration of an increased excretion of urinary dermatan sulfate and heparan sulfate.

CaseERT: N/A

CaseBMT: N/A

Variant1: c.1227dupG (paper says c.1225dupC but according to the variant sequence this should be c.1227dupG - a known variant)

Variant1ClinVarID: 929237

Variant1CAID: CA1139658406

Variant2: c.236C>T (p.A79V)

Variant2ClinVarID: 1458769

Variant2CAID: CA356987

AdditionalVariants: N/A

ParentalGenotype: The transmission of sequence variations found in each patient was inferred by sequencing the corresponding exons of the patient's parents - confirmed in trans by parental testing.
