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]

The c.677A>G (p.H226R) alteration is located in exon 7 (coding exon 6) of the SULT1B1 gene. This alteration results from a A to G substitution at nucleotide position 677, causing the histidine (H) at amino acid position 226 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
