A chromosomal duplication syndrome characterized by cardiomyopathy, corneal clouding or cataracts, hyperlactacidemia, and perinatal death that has_material_basis_in heterozygous duplication within the ATAD3 gene cluster, including the ATAD3A, ATAD3B, and ATAD3C genes, on chromosome 1p36.33 resulting in ATAD3A/ATAD3C gene fusion. Hypotonia, encephalopathy, seizures, and white matter abnormalities are also common.

Signs and symptoms

  • Corneal opacity
  • Bradycardia
  • Neonatal hypotonia
  • Hypertrophic cardiomyopathy
  • Lactic acidosis
  • Abnormal cerebral white matter morphology
  • Encephalopathy
  • EEG abnormality
  • Seizure
  • Flexion contracture

Also known as: CHROMOSOME 1p36.33 DUPLICATION SYNDROME, ATAD3 GENE CLUSTER, AUTOSOMAL DOMINANT
