Fig. 4From: B3GALNT2 mutations associated with non-syndromic autosomal recessive intellectual disability reveal a lack of genotype–phenotype associations in the muscular dystrophy-dystroglycanopathiesOverview of known B3GALNT2 mutations, categorized by clinical phenotype. Effect of the underlined mutations was tested by the complementation assay. The relative activity of tested mutations as determined in the complementation assay (Fig. 3) is indicatedBack to article page
