RCV000177016 | SCV000919530 | pathogenic | Mucopolysaccharidosis, MPS-II | 2018-08-17 | criteria provided, single submitter | clinical testing | Variant summary: IDS c.253G>A (p.Ala85Thr) results in a non-conservative amino acid change located in the Sulfatase, N-terminal domain of the encoded protein sequence. 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. |

RCV000177016 | SCV003445854 | pathogenic | Mucopolysaccharidosis, MPS-II | 2022-06-24 | criteria provided, single submitter | clinical testing | ClinVar contains an entry for this variant (Variation ID: 92617). For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects IDS function (PMID: 17091340). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt IDS protein function. This missense change has been observed in individual(s) with mucopolysaccharidosis II (PMID: 8940265, 25976201, 26762690, 31877959). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 85 of the IDS protein (p.Ala85Thr). |

Uttarilli et al., described it in MPS II patients with attenuated phenotype from Kerala and Karnataka (Uttarilli et al.,2016). Rathmann et al., described A85T initially in one European MPS-II patients with attenuated phenotype (Rathmann et al.,1982). In our study, it was detected in the hemizygous condition in patients with MPS-II attenuated phenotype, hails from from the state of UP and Bihar, India. |
