IllnessMorbus Gaucher, differential diagnosis

Summary

Short information

Comprehensive differential diagnostic panel for Morbus Gaucher comprising 3 guideline-curated genes and altogether 15 curated genes according to the clinical signs.
For specific DD situations supplemental panels are available, e.g. for AR congenital ichthyosis, hydrops fetalis, myoclonic seizures.

Informations about the disease

Clinical Comment

Gaucher disease patients do not produce enough glucocerebrosidase, so glucocerebrosides accumulate in so-called Gaucher cells in the liver, spleen, lungs and bone marrow. Bone damage can be particularly painful; in rare cases Gaucher cells can also accumulate in the brain and lead to the more severe form of the disease. Three forms of Gaucher disease are distinguished. Type 1 is the most common form in the western world (90%), usually with a normal lifespan. Symptoms can start at any age with anaemia, bruising, bleeding, pain and growth disturbances. Type 2 disease is very rare and characterised by damage to the central nervous system, which is usually fatal in the first two to four years of life. Although type 2 occurs worldwide, it is very rare. Type 3 is rare in the West, more common in Asia and in a province of Sweden. In this type, the neurological symptoms develop slowly, usually in childhood, and continue into adulthood. Gaucher disease is transmitted autosomal recessively. Virtually all sequence changes in the GBA gene are point mutations that can be fully detected.

Laboratory requirement

  • Die in grün gezeigten Gene sind kuratiert und werden als Gen-Panel untersucht. Eine Erweiterung des Panels (blau gezeigte Gene, jeweils ebenfalls kuratiert) kann auf Anfrage erfolgen. Sofern unter "Erweitertes Panel" ein Minuszeichen angezeigt wird, sind nur Core-/Basis-Gene verfügbar.

  • Für die Anforderung einer genetischen Untersuchung senden Sie uns bitte die Krankheits-ID auf einem Überweisungsschein. Bitte die Material-Angabe beachten.

  • Für privat versicherte Patienten empfehlen wir einen Antrag auf Kostenübernahme bei der Krankenversicherung.

  • Die Untersuchung wird auch für Selbstzahler angeboten.
