NAGLU |
| Chromosomal Location |
17q21 |
| Allelic Variant 1 |
609701.0003; MUCOPOLYSACCHARIDOSIS TYPE IIIB |
| Identified Mutation |
ARG297TER; In a cell line from a patient with Sanfilippo syndrome type B, GM02552, Zhao et al. [Proc. Natl. Acad. Sci. USA 93:6101-6105 (1996)] identified compound heterozygosity; one of the alleles had a C to T transition at nucleotide 889, resulting in a stop in lieu of arginine at codon 297 (R297X). |

| Allelic Variant 2 |
609701.0004; MUCOPOLYSACCHARIDOSIS TYPE IIIB |
| Identified Mutation |
ARG643HIS; In a cell line from a patient with Sanfilippo syndrome type B, GM02552, Zhao et al. [Proc. Natl. Acad. Sci. USA 93:6101-6105 (1996)] identified compound heterozygosity; one of the alleles had a G to A transition and a substitution of histidine for arginine at codon 643 (R643H).
|
| Remarks |
Deficient N-acetyl-alpha-glucosaminidase; increased urinary heparan sulfate; compound heterozygote; one allele carries a C>T transition in nucleotide 889 (889C>T) in the NAGLU gene, resulting in a stop codon at codon 297 [Arg297ter(R297X)]; the second allele has a mutation resulting in a substitution of histidine for arginine at codon 643 [Arg643His(R643H)] |
