Genes affected
SULT1B1 (HGNC:17845): (sulfotransferase family 1B member 1) Sulfotransferase enzymes catalyze the sulfate conjugation of many hormones, neurotransmitters, drugs, and xenobiotic compounds. These cytosolic enzymes are different in their tissue distributions and substrate specificities. The gene structure (number and length of exons) is similar among family members. However, the total genomic length of this gene is greater than that of other SULT1 genes. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 20, 2024The c.278G>A (p.G93D) alteration is located in exon 4 (coding exon 3) of the SULT1B1 gene. This alteration results from a G to A substitution at nucleotide position 278, causing the glycine (G) at amino acid position 93 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
