Genes affected

DPH1 (HGNC:3003): (diphthamide biosynthesis 1) The protein encoded by this gene is an enzyme involved in the biosynthesis of diphthamide, a modified histidine found only in elongation factor-2 (EEF2). Diphthamide residues in EEF2 are targeted for ADP-ribosylation by diphtheria toxin and Pseudomonas exotoxin A. Defects in this gene have been associated with both ovarian cancer and autosomal recessive intellectual disability with short stature, craniofacial, and ectodermal anomalies.

The c.80G>A (p.R27Q) alteration is located in exon 2 (coding exon 2) of the DPH1 gene. This alteration results from a G to A substitution at nucleotide position 80, causing the arginine (R) at amino acid position 27 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
