Genes affected
SUMF1 (HGNC:20376): (sulfatase modifying factor 1) This gene encodes an enzyme that catalyzes the hydrolysis of sulfate esters by oxidizing a cysteine residue in the substrate sulfatase to an active site 3-oxoalanine residue, which is also known as C-alpha-formylglycine. Mutations in this gene cause multiple sulfatase deficiency, a lysosomal storage disorder. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2009]

Likely pathogenic, criteria provided, single submitterresearchUNC Molecular Genetics Laboratory, University of North Carolina at Chapel Hill-The SUMF1 c.836C>T p.Ala279Val variant is frequently observed in patients with multiple sulfatase deficiency (PMIDs:15146462; 12757706; 18157819; 12757705; 26825355; 25373814; 25885655). Functional studies of this variant show decreased stability and enzyme activity of the encoded protein (PMID:15146462; 18157819). -
Pathogenic, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpAug 06, 2021Variant summary: SUMF1 c.836C>T (p.Ala279Val) results in a non-conservative amino acid change located in the Sulfatase-modifying factor enzyme domain of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 9.2e-05 in 251232 control chromosomes. This frequency is not significantly higher than expected for a pathogenic variant in SUMF1 causing Multiple Sulfatase Deficiency (9.2e-05 vs 0.0011), allowing no conclusion about variant significance. c.836C>T has been reported in the literature in multiple individuals affected with Multiple Sulfatase Deficiency (example, Ahresn_2018, Dierks_2003, Miskin_2016, Prasad _2014, Sabourdy_2015). These data indicate that the variant is very likely to be associated with disease. Multiple publications report experimental evidence evaluating an impact on protein function. The most pronounced variant effect results in low enzyme activity across multiple sulfatases (example, Ahresn_2018, Miskin_2016, Sabourdy_2015). Nine clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation and a majority consensus leaning towards a pathogenic/likely pathogenic outcome (VUS, n=1). Based on the evidence outlined above, the variant was classified as pathogenic. -

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 30, 2023This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 279 of the SUMF1 protein (p.Ala279Val). This variant is present in population databases (rs137852849, gnomAD 0.02%). This missense change has been observed in individuals with multiple sulfatase deficiency (PMID: 12757705, 12757706, 15146462, 18157819, 25373814, 25885655). ClinVar contains an entry for this variant (Variation ID: 2669). 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 not expected to disrupt SUMF1 protein function with a negative predictive value of 80%. Experimental studies have shown that this missense change affects SUMF1 function (PMID: 18157819, 21224894). For these reasons, this variant has been classified as Pathogenic. -
