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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 02, 2024The c.292C>T (p.R98C) alteration is located in exon 4 (coding exon 3) of the SDS gene. This alteration results from a C to T substitution at nucleotide position 292, causing the arginine (R) at amino acid position 98 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
