Abstract
A combined familial study of multiple sclerosis (MS) in England and in the Rostock area of the GDR using the macrophage electrophoretic mobility (MEM)-LAD test embracing 132 relatives has revealed a closely similar pattern of distribution of "anomalous" LAD (Linoleic Acid Depression) values in relatives (77% type of reaction) to that originally reported in the British study. The anomaly in predominantly associated with females--all mothers of MS patients being affected, whilst daughters and sisters are also represented. In addition unusual full MS type of reaction (90% reduction) has been found in some children related to patients. There is clearly a genetic element in the development of MS probably mainfested in the inborn mishandling of unsaturated fatty acids suggested by Thompson; no recognizable pattern of inheritance is noticeable even within the combined material. There is evidence that the metabolic anomaly alone does not inevitably lead to MS, and the full abnormality may be present at an early age. A survey about the examinations and a selection of characteristic family trees of MS are given, illustrating the manner in which the 77% type anomaly is distributed with occasional omission of a generation.
