Аннотация
Having come across a family where the wife of a father who had 47 XYY chromosomes had 5 pregnancies, of which 3 were pathological (one case of anencephaly and spina bifida, one early abortion, one stillborn girl) the authors reviewed the literature concerning the lineage of parents with 47 XYY chromosomes. We have details of a total of 34 subjects who had this caryotype. 10 of them were sterile (30 per cent) and 10 (30 per cent) had a pathological lineage. Only 14 subjects (40 percent) gave rise to a line of normal descendants. The authors discuss the mechanism by which this caryotype (47 XYY) might be transmitted. They point out that so far only few cases have been published and conclude that it is important that many details about this subject should be published so that worthwhile genetic counselling will later be able to be carried out.
