Genes affected

SULT4A1 (HGNC:14903): (sulfotransferase family 4A member 1) This gene encodes a member of the sulfotransferase family. The encoded protein is a brain-specific sulfotransferase believed to be involved in the metabolism of neurotransmitters. Polymorphisms in this gene may be associated with susceptibility to schizophrenia. [provided by RefSeq, Jul 2008]

The c.814A>C (p.K272Q) alteration is located in exon 7 (coding exon 7) of the SULT4A1 gene. This alteration results from a A to C substitution at nucleotide position 814, causing the lysine (K) at amino acid position 272 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
