Genes affected
SULF1 (HGNC:20391): (sulfatase 1) This gene encodes an extracellular heparan sulfate endosulfatase. The encoded enzyme selectively removes 6-O-sulfate groups from heparan sulfate chains of heparan sulfate proteoglycans (HSPGs). The enzyme is secreted through the Golgi and is subsequently localized to the cell surface. The expression of this gene may be down-regulated in several types of cancer, including hepatocellular (HCC), ovarian and breast cancers. Alternative splicing results in multiple transcript variants.

Submissions by phenotype

not specified Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.2194C>T (p.R732W) alteration is located in exon 19 (coding exon 15) of the SULF1 gene. This alteration results from a C to T substitution at nucleotide position 2194, causing the arginine (R) at amino acid position 732 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 10, 2023This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 732 of the SULF1 protein (p.Arg732Trp). This variant is present in population databases (rs754254864, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with SULF1-related conditions. ClinVar contains an entry for this variant (Variation ID: 282083). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
