RCV001578306 | SCV001547776 | likely pathogenic | Mucopolysaccharidosis, MPS-IV-A | 2021-02-01 | criteria provided, single submitter | research | The prevalence of the variant in affected individuals is significantly increased compared with the prevalence in controls (PS4_supporting); located in a mutational hot spot and/or critical and well-established functional domain without benign variation (PM1_moderate); absent from gnomAD v2.1.1 (PM2_moderate); multiple lines of computational evidence support a deleterious effect on the gene (PP3_supporting) |

RCV001731366 | SCV001983494 | uncertain significance | not specified | 2021-09-14 | criteria provided, single submitter | clinical testing | Variant summary: GALNS c.707A>G (p.His236Arg) results in a non-conservative amino acid change located in the Sulfatase, N-terminal (IPR000917) 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 251390 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.707A>G has been reported in the literature as a compound heterozygous genotype with c.281G>T (p.Arg94Leu) in at-least one individual affected with a confirmed molecular and biochemical diagnosis of Mucopolysaccharidosis Type IVA (Morquio Syndrome A), from Ceara state of the Northeastern region of Brazil who underwent full gene sequencing for the GALNS gene (example, Bochernistan_2018, PMID not available). These data do not allow any conclusion about variant significance. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation and classified the variant as likely pathogenic. Based on the evidence outlined above, until additional clinical/functional evidence is obtained, the variant was classified as uncertain significance. |
