    Abstract:
    Mucopolysaccharidosis type IVA (MPS IVA) is a rare genetic disease caused by mutations in the GALNS gene and is inherited in an autosomal recessive manner. GALNS encodes N-acetylgalactosamine-6-sulfatase that breaks down certain complex carbohydrates known as glycosaminoglycans (GAGs). Deficiency in this enzyme causes accumulation of GAGs in lysosomes of body tissues. A human induced pluripotent stem cell (iPSC) line was generated from dermal fibroblasts of a MPS IVA patient that has compound heterozygous mutations (p.R61W and p.WT405del) in the GALNS gene. This iPSC line offers a useful resource to study the disease pathophysiology and a cell-based model for drug development.
