Investigating the Utility of Leukocyte Sialic Acid Measurements in Lysosomal Free Sialic Acid Storage Disorder

ABSTRACT Lysosomal free sialic acid storage disorder (FSASD) is a rare, multisystem neurodegenerative disease caused by biallelic pathogenic variants in SLC17A5, encoding sialin. FSASD is characterized by aberrant accumulation of unconjugated “free” sialic acid (Neu5Ac) within lysosomes. Depending o...
