Genes affected

DLST (HGNC:2911): (dihydrolipoamide S-succinyltransferase) This gene encodes a mitochondrial protein that belongs to the 2-oxoacid dehydrogenase family. This protein is one of the three components (the E2 component) of the 2-oxoglutarate dehydrogenase complex that catalyzes the overall conversion of 2-oxoglutarate to succinyl-CoA and CO(2). Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Oct 2011]

The c.7T>C (p.S3P) alteration is located in exon 1 (coding exon 1) of the DLST gene. This alteration results from a T to C substitution at nucleotide position 7, causing the serine (S) at amino acid position 3 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
