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]

Dec 20, 2023

The c.383C>T (p.A128V) alteration is located in exon 5 (coding exon 4) of the DNAJC24 gene. This alteration results from a C to T substitution at nucleotide position 383, causing the alanine (A) at amino acid position 128 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
