Case#: Patient 109, Far East district of the Russian Federation

DiseaseAssertion: MPS1, Severe

FamilyInfo:

CasePresentingHPOs:

CaseHPOFreeText: IdA activity in DBS=0,01 leukocytes, severe phenotype, hyperexcretion of urine heparan and dermatan sulfate

CaseNotHPOs:

CaseNotHPOFreeText:

CasePreviousTesting: Electrophoresis of urine GAGs and measurement of lysosomal enzyme activity in peripheral blood leukocytes or DBSs were performed for all patients with suspected MPS I

GenotypingMethod: The 14 exons and exon–intron boundaries of the IDUA gene were amplified from DNA samples. Sanger sequencing of each one of the 14 exons was performed. PCR products containing mutations were re-sequenced in both directions. The mutations were further confirmed where possible by restriction analysis (data not shown).
