Genes affected

SULT1A1 (HGNC:11453): (sulfotransferase family 1A 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. This gene encodes one of two phenol sulfotransferases with thermostable enzyme activity. Multiple alternatively spliced variants that encode two isoforms have been identified for this gene.

The c.26G>A (p.R9H) alteration is located in exon 2 (coding exon 1) of the SULT1A1 gene. This alteration results from a G to A substitution at nucleotide position 26, causing the arginine (R) at amino acid position 9 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
