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]

SUMF1 (HGNC:):

ACMG classification

Verdict is Pathogenic. Variant got 10 ACMG points.

• PM1: In a disulfide_bond (size 147) in uniprot entity SUMF1_HUMAN there are 4 pathogenic changes around while only 0 benign (100%) in NM_182760.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.994
• PP5: Variant 3-4417229-C-G is Pathogenic according to our data. Variant chr3-4417229-C-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 371554.Status of the report is criteria_provided_single_submitter, 1 stars.
