Genes affected
OVCA2 (HGNC:24203): (OVCA2 serine hydrolase domain containing) Involved in response to retinoic acid. Located in cytoplasm. Biomarker of ovarian cancer. [provided by Alliance of Genome Resources, Apr 2022]
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. [provided by RefSeq, Oct 2016]
DPH1 Gene-Disease associations (from GenCC):
  • developmental delay with short stature, dysmorphic facial features, and sparse hair
    Inheritance: AR Classification: DEFINITIVE Submitted by: ClinGen
  • craniofacial dysplasia-short stature-ectodermal anomalies-intellectual disability syndrome
    Inheritance: AR Classification: STRONG, MODERATE, SUPPORTIVE Submitted by: Ambry Genetics, PanelApp Australia, Orphanet
