Genes affected

DPH7 (HGNC:25199): (diphthamide biosynthesis 7) Diphthamide is a post-translationally modified histidine residue present in elongation factor 2, and is the target of diphtheria toxin. This gene encodes a protein that contains a WD-40 domain, and is thought to be involved in diphthamide biosynthesis. A similar protein in yeast functions as a methylesterase, converting methylated diphthine to diphthine, which can then undergo amidation to produce diphthamide. [provided by RefSeq, Oct 2016]

The c.1298T>G (p.L433R) alteration is located in exon 9 (coding exon 9) of the DPH7 gene. This alteration results from a T to G substitution at nucleotide position 1298, causing the leucine (L) at amino acid position 433 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
