Background: The mucopolysaccharidoses (MPSs) are very rare lysosomal diseases. MPSs belong to inherited diseases; however, newborns are usually asymptomatic. A deficiency of one of the enzymes, which is responsible for glycosaminoglycan (GAG) catabolism, results in the accumulation of this material.

Mucopolysaccharidosis is a rare lysosomal storage disease caused by deficiencies in enzymes involved in the degradation of glycosaminoglycans. We report the case of an adult with mucopolysaccharidosis type II who developed respiratory insufficiency after brain metastasectomy for extraskeletal Ewing sarcoma. This report describes the case of a 35-year-old man with a mass on the left chest wall for 3 months.

Article Synopsis
  • Mucopolysaccharidosis type II (MPS II) is a rare genetic disorder caused by mutations in the IDS gene, leading to reduced enzyme activity and the accumulation of harmful substances in cells, affecting multiple body systems.
  • Symptoms of MPS II include distinctive facial features, skeletal abnormalities, respiratory issues, and hernias, and diagnosis involves clinical evaluation, imaging, lab tests, and genetic analysis.
  • Treatment mainly focuses on managing symptoms, as options like enzyme replacement therapy and stem cell transplantation are limited by costs and availability, resulting in high misdiagnosis rates in places like China.

Lysosomal storage diseases are a group of rare hereditary metabolic diseases. Due to a deficiency of lysosomal enzymes, complex substrates accumulate in the lysosomes of various organs. Depending on the affected enzyme, this results in clinically variable and chronic progressive multiorgan diseases.

Phenylketonuria (PKU), hereditary tyrosinemia type 1 (HT1), and mucopolysaccharidosis type 1 (MPSI) are autosomal recessive disorders linked to the phenylalanine hydroxylase () gene, fumarylacetoacetate hydrolase () gene, and alpha-L-iduronidase () gene, respectively. Potential therapeutic strategies to ameliorate disease include corrective editing of pathogenic variants in the and genes and, as a variant-agnostic approach, inactivation of the 4-hydroxyphenylpyruvate dioxygenase () gene, a modifier of HT1, via adenine base editing. Here we evaluated the off-target editing profiles of therapeutic lead guide RNAs (gRNAs) that, when combined with adenine base editors correct the recurrent P281L variant, R408W variant, or W402X variant or disrupt the gene in human hepatocytes.
