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]

Aug 30, 2021

The c.1058C>T (p.S353L) alteration is located in exon 9 (coding exon 9) of the DPH7 gene. This alteration results from a C to T substitution at nucleotide position 1058, causing the serine (S) at amino acid position 353 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
