Genes affected

SULT1A2 (HGNC:11454): (sulfotransferase family 1A member 2) 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. Two alternatively spliced variants that encode the same protein have been described.

Collection Method: clinical testing

The c.796A>G (p.T266A) alteration is located in exon 8 (coding exon 7) of the SULT1A2 gene. This alteration results from a A to G substitution at nucleotide position 796, causing the threonine (T) at amino acid position 266 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
