    Notes: A successful pregnancy in a woman with Turner's syndrome with a 45, X/46,XX karyotype is described. The literature contains reports of a total of nine pregnancies in seven women with a 45,X karyotype and 56 pregnancies in 23 women with mosaicism and a 45,X cell line, as well as a 46,XX and/or 47,XXX cell line. Fifteen of the latter 56 pregnancies ended in spontaneous abortion (27 per cent), and four ended in the delivery of a stillborn child; 12 of the 37 liveborn infants (32 per cent) had a physical or mental abnormality, and 8 (22 per cent) had a chromosome abnormality. Three had Down's syndrome, and five had a 45,X cell line. Due to the relatively high (8 per cent) incidence of Down's syndrome among liveborn infants of women with Turner's syndrome, amniocentesis for fetal karyotyping should be advised.

    Notes: Summary Chromosome analysis has been made of 11 148 children; 29 had sex chromosome abnormalities (2.60 per 1000) and 64 autosomal abnormalities (5.74 per 1000). The total incidence of major chromosome abnormalities was 8.34 per 1000. The incidence of chromosome variations was 16.8 per 1000. The most common variants were those with variation in size of short arms-satellites in D and G chromosomes and variations in Y chromosome size. So far, very little is known about the significance of such chromosome variations. The incidence of most chromosome abnormaliies in liveborn children is well established by now from studies of a total of 54749 consecutively liveborn children in 6 studies as shown in Table 1. More chromosome studies of liveborn children are, however, needed for several purposes such as finding families with chromosome translocations, studying segregation rates and giving genetic advice to families with inheritable chromosome aberrations and an increased risk of getting children with unbalanced chromosome abnormalities, mental retardation and physical abnormalities. One of the main purposes in chromosome examination of newborn children is to study the development of children with different chromosome abnormalities, especially those with sex chromosome abnormalities, and compare them with controls, treat them when needed and give advice to the parents of such children.

    Notes: Summary Before the introduction of the banding technique we studied a boy presented as a case of 47,XY,?Yq- (Christensen and Nielsen, 1971). The case has been restudied with the use of different types of banding, which revealed the following karyotype 47,X,del(X) (p11→q13::q21→q24),del(Y) (q11).

    Notes: Summary Follow-up examination of 15 unselected children with aneuploid sex chromosome abnormalities has been made till between the age of 21/2 and 5 years. The mental development of the 15 children was in all cases within the normal range, but there was a tendency to some differences compared with their siblings.

    Notes: Summary An 11-year-old girl with karyotype 45,X/46,X,dic(X) (Xqter→p22::p22→qter) is presented. The abnormal X is always found to be the inactive and late replicating X, and according to previous investigations by Therman et al. (1974) part of the cells are seen to have bipartite Barr bodies.

    Notes: Abstract Cytogenetic examination of a 14, year, old severely retarded girl revealed a karyotype of 47 chromosomes with an extra bisatellited chromosome, a translocation between No. 22 and a chromosome in the D group. The girl had presented an early autistic syndrome beginning about 6 months of age during plastering for a congen ital luxation of the hips and receding from the age of 5. In addition, she was hyperkinetic with various aggressive and autoaggressive traits and had atypical minor epileptic fits. Data from child psychiatric examinations at 5 and 14 years are presented. The importance of giving parents information as early as possible about biological causes of mental retardation and mental illness is stressed.
