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]

The c.1631G>A (p.R544H) 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 1631, causing the arginine (R) at amino acid position 544 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 544 of the ARSI protein (p.Arg544His). 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 output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 661582). This variant has not been reported in the literature in individuals affected with ARSI-related conditions. This variant is present in population databases (rs763136370, gnomAD 0.02%). -
