Persistent elevations of alkaline phosphatase as an early indicator of GM1 gangliosidosis.
Journal Article Mol Genet Metab Rep · March 2025 GLB1-related disorders are autosomal recessive lysosomal diseases caused by enzymatic deficiency of β-galactosidase. Enzymatic deficiency of β-galactosidase may lead to one of two phenotypes, GM1 gangliosidosis or mucopolysaccharidosis IVB (MPS IVB). GM1 g ...

Journal Article Curr Protoc · February 2025 Mucopolysaccharidoses (MPSs) are complex lysosomal diseases that result in the accumulation of glycosaminoglycans (GAGs) in urine, blood, and tissues. Lysosomal enzymes responsible for GAG degradation are defective in MPSs. GAGs including chondroitin sulfa ...
