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]

Aug 23, 2021

The c.425C>T (p.T142I) alteration is located in exon 7 (coding exon 7) of the DLST gene. This alteration results from a C to T substitution at nucleotide position 425, causing the threonine (T) at amino acid position 142 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
