    Notes: Summary The recessive mutation, rachiterata, reduces the number of cervical vertebrae to 6 by shifting the cervico-thoracic boundary in a cranial direction, and produces partial duplication of the neural arch of the axis. Rachiterata also produces malformations of thoraco-lumbar vertebrae, often associated with fusions of ribs. These malformations are caused by a disturbed arrangement of somites first detectable in 11-day embryos.

    Description / Table of Contents: Zusammenfassung Eine genetische Studie in einer Familie mit der adulten Form der metachromatischen Leukodystrophie (MLD) ging von einem 25jährigen Probanden mit den charakteristischen biochemischen Zeichen der Erkrankung aus: Weitgehender Mangel der Arylsulfatase A in den Leukocyten und im Urin, erhöhte Sulfatidausscheidung im Urin. Die Eltern des Patienten zeigten als heterozygote Überträger der Erkrankung etwa halbnormale Arylsulfatase-A-Spiegel in den Leukocyten. Dieser Befund wurde auch bei vier weiteren Familienmitgliedern erhoben. Die enzymatische Identifizierung nicht-obligater heterozygoter Überträger liefert eine relativ zuverlässige Basis für die genetische Beratung der Familienmitglieder.
    Notes: Summary A family with the adult form of metachromatic leucodystrophy (MLD) was genetically studied starting from a proband aged 25 years with the characteristic biochemical signs of the disease: profound deficiency of arysulfatase A in leucocytes and urine, and high sulfatide excretion in urine. The patient's parents, who were obligate heterozygous carriers of the disease, showed about half the normal level of arylsulfatase A in their leucocytes as did four other members of the family. The enzymatic identification of non-obligate heterozygous carriers provides a relatively reliable basis for genetic counselling of family members.
