Genes affected

SDS (HGNC:10691): (serine dehydratase) This gene encodes one of three enzymes that are involved in metabolizing serine and glycine. L-serine dehydratase converts L-serine to pyruvate and ammonia and requires pyridoxal phosphate as a cofactor. The encoded protein can also metabolize threonine to NH4+ and 2-ketobutyrate. The encoded protein is found predominantly in the liver. [provided by RefSeq, Jul 2008]

The c.289G>A (p.E97K) alteration is located in exon 4 (coding exon 3) of the SDS gene. This alteration results from a G to A substitution at nucleotide position 289, causing the glutamic acid (E) at amino acid position 97 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
