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.

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 177 of the SULF1 protein (p.Gly177Ser). This variant is present in population databases (rs538017286, gnomAD 0.005%). This missense change has been observed in individual(s) with ocular developmental anomalies (PMID: 26893459). ClinVar contains an entry for this variant (Variation ID: 221945). 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. -
