Genes affected

ARSI (HGNC:32521): (arylsulfatase family member I) This gene encodes a protein that belongs to a large family of sulfatases that hydrolyze sulfate esters and sulfamates. Members of this family play a role in several cellular processes, including hormone synthesis, cell signaling in development and degradation of macromolecules. The protein encoded by this gene is thought to be secreted, and to function in extracellular space. [provided by RefSeq, Jul 2016]

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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with ARSI-related conditions. This variant is present in population databases (rs771311478, ExAC 0.02%). This sequence change replaces arginine with histidine at codon 497 of the ARSI protein (p.Arg497His). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and histidine. -

The c.1490G>A (p.R497H) alteration is located in exon 2 (coding exon 2) of the ARSI gene. This alteration results from a G to A substitution at nucleotide position 1490, causing the arginine (R) at amino acid position 497 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
