Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 169233 control chromosomes (gnomAD). c.253G>A has been reported in the literature in multiple individuals affected with Mucopolysaccharidosis Type II (Hunter Syndrome)(Alkhzouz_2016, Amartino_2014, Dvorakova_2017, Kosuga_2016). These data indicate that the variant is very likely to be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function. The most pronounced variant effect results in <10% of normal activity (Alkhzouz_2016). No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as pathogenic.
