Integrated Genetics/Laboratory Corporation of America RCV000001638 SCV000919840 pathogenic Mucopolysaccharidosis, MPS-III-B 2017-11-20 criteria provided, single submitter clinical testing Variant summary: The NAGLU c.700C>T (p.Arg234Cys) variant located in the alpha-n-acetylglucosaminidase, tim-barrel domain (via InterPro) involves the alteration of a conserved nucleotide and 4/4 in silico tools predict a damaging outcome for this variant (SNPsandGO not captured due to low reliability index). This variant was found in 10/276804 control chromosomes (gnomAD and publication controls) at a frequency of 0.0000361, which does not exceed the estimated maximal expected allele frequency of a pathogenic NAGLU variant (0.0025). Multiple publications have cited the variant in compound heterozygote and homozygote MPS IIIB pts and found NAGLU activity to be significantly decreased (Mangas_2008). In addition, a reputable database, OMIM classifies the variant as "pathogenic." Taken together, this variant is classified as pathogenic.
