HistoryThis section has been translated automatically.

EtiopathogenesisThis section has been translated automatically.
Autosomal dominant inheritance, low penetrance, variable expressivity. Among other things, mutations at the 9q22 gene locus (SPTLC1 gene) are discussed, which lead to defects of the enzyme serine-palmitoyltransferase (SPT). Other families have been associated with mutations at the 3q13-22 gene locus.
ManifestationThis section has been translated automatically.
2nd to 3rd decade of life, rarely in childhood. Male sex preferred.
LocalizationThis section has been translated automatically.
Lower extremities, less pronounced also upper extremities.
Clinical featuresThis section has been translated automatically.
Symmetrically arranged, stocking-shaped sensory disturbances for pain, temperature and touch, occasionally pyramid signs (Babinski positive). Often weakened tendon reflexes. Painless ulcers, initially mostly on one side, later on both sides, especially in areas under pressure. Acrocyanosis and swelling of fingers and toes. Acroosteolyses, osteoporosis, possibly muscular atrophies, flat feet, splayfeet.
Differential diagnosisThis section has been translated automatically.
TherapyThis section has been translated automatically.
Symptoms: Avoidance of local mechanical stimuli and pressure points (e.g. orthopaedic shoes), instruction for daily detailed self-examination for the smallest injuries, treatment of the ulcers with anti-infectious and wound healing promoting substances, see below wound treatment. Cooperation with neurologists and orthopaedic surgeons.
Progression/forecastThis section has been translated automatically.
Slowly progressive course, usually relatively benign (no pronounced mutilations).
