CaseERT: Yes - the patient had been treated with intravenous rhIDU for 13 years before IT rhIDU and had not undergone HSCT. The patient was also enrolled concurrently in an IRB approved non‐interventional longitudinal study of brain structure and function in MPS at the University of Minnesota. He showed stable or improved neurocognitive outcomes after 24 months of IT rhIDU. The patient showed the greatest improvement in his ability to encode verbal stimuli, moving from significantly impaired to the average level. This was accompanied by a significant improvement in adaptive behavior and an improvement to an above average level, in his ability to remember verbal material in a context. Nonverbal memory, both encoding and recall increased although those scores remained below the average range. A baseline of average IQ and attention performance also somewhat improved.

CaseIII-1: Male, China, Asian, 51 years report

CasePresentingHPOs: HP:0001962, HP:0100749, HP:0002094, HP:0500020, HP:0031185, HP:0004755, HP:0031295, HP:0011103 (Heart palpitations, Chest pain, Dyspnea, Abnormal cardiac biomarker test, Increased NT-proBNP level, Supraventricular tachycardia, Left atrial enlargement, Abnormality of the left ventricular outflow tract)

HPOsFreeText: Experienced palpitations for 9 years, Chest pain and mild dyspnea for 2 years, Slightly elevated cardiac troponin T level of 21.8 ng/L (normal 0 to 14 ng/L), Significantly elevated N-terminal pro-brain natriuretic peptide level of 537 pg./mL (normal 0 to 125 pg/mL), ECG showed non-specific ST_T change, Preserved biventricular systolic function, Severe LV outflow tract obstruction (peak aortic outflow velocity = 4.8 m/s, peak gradient = 92 mmHg), Proband had a sigmoid septum with LV outflow tract obstruction and LV mass index to body surface area (BSA) of 87.2 g/m2

CaseNotHPOs: HP:0001677 (Coronary artery disease)

NotHPOsFreeText: N/A

CaseAddInfo:

CaseGenotypingMethod: Genomic DNA was acquired from the proband and all surviving members of his extended family. These were all tested by a 117 gene screening panel that were connected to Cardiomyopathy. The results were confirmed by Sanger sequencing and the variants found were filtered for pathogenicity.

Variant: NM_000257.3:c.4130C>T (p.Thr1377Met)

CaseNotHPOs: N/A

NotHPOsFreeText: N/A

CaseAddInfo: Mutation is classified as de novo

CasePreviousTesting: See list of 26 genes under Target sequence capture sequencing

CaseGenotypingMethod: Genomic DNA was extracted from the proband and other family members. Afterwards, it was subject to PCR amplification and sequencing. Any variants found were confirmed with Sanger sequencing before being filtered for pathogenicity.
