Genes affected
DPH2 (HGNC:3004): (diphthamide biosynthesis 2) This gene is one of two human genes similar to the yeast gene dph2. The yeast gene was identified by its ability to complement a diphthamide mutant strain, and thus probably functions in diphthamide biosynthesis. Diphthamide is a post-translationally modified histidine residue present in elongation factor 2 (EF2) that is the target of diphtheria toxin ADP-ribosylation. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2016]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 06, 2021The c.692A>G (p.D231G) alteration is located in exon 4 (coding exon 4) of the DPH2 gene. This alteration results from a A to G substitution at nucleotide position 692, causing the aspartic acid (D) at amino acid position 231 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
