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]

Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Dec 04, 2023	This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 155 of the SUMF1 protein (p.Ser155Pro). This variant is present in population databases (rs137852850, gnomAD 0.2%). This missense change has been observed in individual(s) with multiple sulfatase deficiency (PMID: 12757706, 16125993, 21224894, 25885655, 27344646). ClinVar contains an entry for this variant (Variation ID: 2672). 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 SUMF1 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects SUMF1 function (PMID: 15146462, 17657823, 21224894). For these reasons, this variant has been classified as Pathogenic. -

Pathogenic, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Mar 02, 2017	Variant summary: The SUMF1 c.463T>C (p.Ser155Pro) variant involves the alteration of a conserved nucleotide. 3/4 in silico tools predict a damaging outcome for this variant (SNPs&GO not captured due to low reliability index). This variant was found in 5/121384 control chromosomes at a frequency of 0.0000412, which does not exceed the estimated maximal expected allele frequency of a pathogenic SUMF1 variant (0.001118). The variant was reported in numerous affected individuals in the literature in both the homozygous and compound heterozygous state, and functional evidence has showed patients have a drastic reduction in sulfatase activity compared to wild-type. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic/likely pathogenic. Taken together, this variant is classified as pathogenic. -
