    Description / Table of Contents: Zusammenfassung In den meisten Fallbeschreibungen stützt sich die Diagnose der PMK vorwiegend auf den pathologisch-anatomischen Befund. Am Beispiel einer weiteren Familie mit PMK, die ausschließlich auf Grund des genetischen, klinischen und hirnbioptischen Befundes diagnostiziert wurde, wird dargelegt, daß das klassische klinisch und genetisch definierte Krankheitssyndrom für die Diagnose ein zuverlässigeres Kriterium bildet als der variationsreiche pathologische Befund.
    Notes: Abstract In most case-reports the diagnosis of Pelizaeus-Merzbacher disease is only made on morphological grounds without taking into consideration that the clinical and genetical findings of these cases were often incomplete. With the report of a new family with PM.-disease, where the diagnosis was made exclusively on the basis of clinical and genetical findings as well as brain biopsies, we want to point out, that the classical clinically and genetically defined syndrome is a more reliable criterium for making a diagnosis than the rather variable pathological findings.

    Notes: Abstract This is the report of two independent families in which a balanced maternal translocation led to trisomy 12p in one of each their offspring. Evaluation of 21 further case reports indicates that this is a phenotypically well defined syndrome which leads to severe developmental retardation. It can be recognized by a characteristic combination of craniofacial anomalies which are summarized in a phantom picture. The gene sequences which produce the typical features in the trisomic state must be localized distally to band 12p 12, which is the breakpoint in the partial trisomies. The specific craniofacial anomalies are not visibly modified by the length of the trisomic segment or additional small monosomies or trisomies of recipient chromosomes. However, the frequency and severity of organ malformations and the resulting probability of survival seem to decrease with increasing degrees of chromosomal imbalance. A cytogenetic classification of the 21 inherited translocations and a segregation analysis from the pedigree data was performed. For the different types of translocations the calculated risk figures are given.
