Conditions

Glycogen Storage Disease Type IA, Ornithine Transcarbamylase Deficiency, Wilson Disease

Brief summary

The objective of this observational study is to evaluate the seroprevalence of anti-AAV antibodies in subjects with Ornithine Transcarbamylase (OTC) deficiency, Glycogen Storage Disease Type Ia (GSDIa), and Wilson Disease

Detailed description

The study is primarily designed to follow a virtual model, in which Screening will take place over a telephone/video call. The study will comprise a single home health visit, either on the same day as Screening or within 30 days of enrollment. A safety follow-up may occur up to 5 days after Day 1 assessments are completed.
