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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 25, 2024The c.700C>T (p.L234F) alteration is located in exon 6 (coding exon 6) of the UST gene. This alteration results from a C to T substitution at nucleotide position 700, causing the leucine (L) at amino acid position 234 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
