Genes affected

ARSH (HGNC:32488): (arylsulfatase family member H) Sulfatases, such as ARSH, hydrolyze sulfate esters from sulfated steroids, carbohydrates, proteoglycans, and glycolipids. They are involved in hormone biosynthesis, modulation of cell signaling, and degradation of macromolecules (Sardiello et al., 2005 [PubMed 16174644]).[supplied by OMIM, Mar 2008]

Collection Method: clinical testing

The c.298G>A (p.A100T) alteration is located in exon 3 (coding exon 3) of the ARSH gene. This alteration results from a G to A substitution at nucleotide position 298, causing the alanine (A) at amino acid position 100 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
