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: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with ARSI-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with tryptophan at codon 481 of the ARSI protein (p.Arg481Trp). The arginine residue is moderately conserved and there is a moderate physicochemical difference between arginine and tryptophan. -
