Autosomal dominant conditions

Autosomal dominant conditions

Autosomal recessive conditions are often thought to be 'metabolic' as opposed to autosomal dominant conditions being 'structural', notable exceptions:
  • some 'metabolic' conditions such as Hunter's and G6PD are X-linked recessive whilst others such as hyperlipidaemia type II and hypokalaemic periodic paralysis are autosomal dominant
  • some 'structural' conditions such as ataxia telangiectasia and Friedreich's ataxia are autosomal recessive

The following conditions are autosomal dominant:
  • Achondroplasia
  • Acute intermittent porphyria
  • Adult polycystic disease
  • Antithrombin III deficiency
  • Ehlers-Danlos syndrome
  • Familial adenomatous polyposis
  • Hereditary haemorrhagic telangiectasia
  • Hereditary spherocytosis
  • Hereditary non-polyposis colorectal carcinoma
  • Huntington's disease
  • Hyperlipidaemia type II
  • Hypokalaemic periodic paralysis
  • Malignant hyperthermia
  • Marfan's syndromes
  • Myotonic dystrophy
  • Neurofibromatosis
  • Noonan syndrome
  • Osteogenesis imperfecta
  • Peutz-Jeghers syndrome
  • Retinoblastoma
  • Romano-Ward syndrome
  • tuberous sclerosis
  • Von Hippel-Lindau syndrome
  • Von Willebrand's disease*

*type 3 von Willebrand's disease (most severe form) is inherited as an autosomal recessive trait. Around 80% of patients have type 1 disease
