Mucopolysaccharidosis type IIIB (MPS IIIB) is an autosomal recessive metabolic disorder caused by mutations in NAGLU gene, and characterized by progressive cognitive decline and behavioral difficulties and motor function retardation. A human induced pluripotent stem cell line, SDQLCHi041-A was generated from peripheral blood mononuclear cells of a 4 years and 9 months old patient with MPS IIIB, who carried compound heterozygous mutation of c.1336G > A and c.608G > A in NAGLU gene. SDQLCHi041-A offers a useful cell model to investigate pathogenic mechanisms in MPS IIIB.
