Storage Diseases Variant Curation Expert Panel

Our main goal is to curate genes and variants involved in metabolic storage diseases. Initially, we are focusing efforts on modification of the ACMG-AMP criteria for interpretation of variants within GAA. Deficiency of acid alpha-glucosidase, encoded by GAA, causes Pompe disease (glycogen storage disease type II; acid maltase deficiency). Accurate interpretation of variants within GAA is important for confirmation of the diagnosis in symptomatic patients of any age, asymptomatic infants identified by newborn screening, as well as testing for family members.
