Genes affected

ARSD (HGNC:717): (arylsulfatase D) The protein encoded by this gene is a member of the sulfatase family. Sulfatases are essential for the correct composition of bone and cartilage matrix. The encoded protein is postranslationally glycosylated and localized to the lysosome. This gene is located within a cluster of similar arylsulfatase genes on chromosome X. A related pseudogene has been identified in the pseudoautosomal region of chromosome Y. [provided by RefSeq, Jul 2011]

Collection Method: clinical testing

The c.1468G>A (p.E490K) alteration is located in exon 10 (coding exon 10) of the ARSD gene. This alteration results from a G to A substitution at nucleotide position 1468, causing the glutamic acid (E) at amino acid position 490 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
