Genes affected
UST (HGNC:17223): (uronyl 2-sulfotransferase) Uronyl 2-sulfotransferase transfers sulfate to the 2-position of uronyl residues, such as iduronyl residues in dermatan sulfate and glucuronyl residues in chondroitin sulfate (Kobayashi et al., 1999 [PubMed 10187838]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 12, 2023The c.662G>A (p.R221K) alteration is located in exon 5 (coding exon 5) of the UST gene. This alteration results from a G to A substitution at nucleotide position 662, causing the arginine (R) at amino acid position 221 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
