Genes affected

ARSG (HGNC:24102): (arylsulfatase G) The protein encoded by this gene belongs to the sulfatase enzyme family. Sulfatases hydrolyze sulfate esters from sulfated steroids, carbohydrates, proteoglycans, and glycolipids. They are involved in hormone biosynthesis, modulation of cell signaling, and degradation of macromolecules. This protein displays arylsulfatase activity at acidic pH, as is typical of lysosomal sulfatases, and has been shown to localize in the lysosomes. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jun 2012]

ARSG Gene-Disease associations (from GenCC):

• Usher syndrome, type 4

  Inheritance: AR Classification: STRONG, MODERATE, LIMITED Submitted by: Genomics England PanelApp, G2P, Ambry Genetics, Labcorp Genetics (formerly Invitae)
• Usher syndrome type 3

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.449 is higher than 0.05.
