Genes affected

SLC16A6 (HGNC:10927): (solute carrier family 16 member 6) Predicted to enable monocarboxylic acid transmembrane transporter activity. Predicted to be involved in monocarboxylic acid transport. Predicted to be located in membrane. Predicted to be integral component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

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]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.862

Apr 09, 2024

The c.889T>C (p.Y297H) alteration is located in exon 6 (coding exon 4) of the SLC16A6 gene. This alteration results from a T to C substitution at nucleotide position 889, causing the tyrosine (Y) at amino acid position 297 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
