Genes affected

OGDHL (HGNC:25590): (oxoglutarate dehydrogenase L) The protein encoded by this gene is similar to oxoglutarate dehydrogenase (OGDH) of the OGDH complex, which degrades glucose and glutamate. This gene encodes several isoforms, including some that appear to localize to mitochondria. The encoded protein down-regulates the AKT signaling cascade and can suppress the growth of cervical cancer cells. [provided by RefSeq, Dec 2016]

The c.2381A>G (p.D794G) alteration is located in exon 18 (coding exon 17) of the OGDHL gene. This alteration results from a A to G substitution at nucleotide position 2381, causing the aspartic acid (D) at amino acid position 794 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
