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.1313C>T (p.S438F) 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 1313, causing the serine (S) at amino acid position 438 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
