Genes affected

DPH5 (HGNC:24270): (diphthamide biosynthesis 5) This gene encodes a component of the diphthamide synthesis pathway. Diphthamide is a post-translationally modified histidine residue found only on translation elongation factor 2. It is conserved from archaebacteria to humans, and is targeted by diphtheria toxin and Pseudomonas exotoxin A to halt cellular protein synthesis. The yeast and Chinese hamster homologs of this protein catalyze the trimethylation of the histidine residue on elongation factor 2, resulting in a diphthine moiety that is subsequently amidated to yield diphthamide. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Ambry Genetics

Nov 18, 2023

The c.299A>T (p.K100M) alteration is located in exon 4 (coding exon 3) of the DPH5 gene. This alteration results from a A to T substitution at nucleotide position 299, causing the lysine (K) at amino acid position 100 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
