Genes affected
DNAJC24 (HGNC:26979): (DnaJ heat shock protein family (Hsp40) member C24) Diphthamide is a unique posttranslationally modified histidine found only in translation elongation factor-2 (EEF2; MIM 130610). This modification is conserved from archaebacteria to humans and serves as the target for ADP-ribosylation and inactivation of EEF2 by diphtheria toxin (DT) and Pseudomonas exotoxin A. DPH4 is 1 of several enzymes involved in synthesis of diphthamide in EEF2 (Liu et al., 2004 [PubMed 15485916]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 16, 2023The c.203T>G (p.I68S) alteration is located in exon 3 (coding exon 2) of the DNAJC24 gene. This alteration results from a T to G substitution at nucleotide position 203, causing the isoleucine (I) at amino acid position 68 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
