Family trauma through generations: incest and domestic violence in rural Sweden in the nineteenth century.

Two generations of a family who lived in mid-nineteenth rural Sweden are described. Domestic violence was a common feature in the first generation family. The salient feature there was undoubtedly the incestuous father-daughter relationships.

Polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy (PLO-SL): a genealogical study of Swedish families of probable Finnish background.

Four Swedish families in northern Sweden with polycystic lipomembranous osteodysplasia (PLO-SL) were studied genealogically. Historical and genealogical date provided evidence for a Finnish origin. Both parents of two of the families could be traced back to Finnish ancestors, and the other two families had a common origin in a region with a known Finnish influence, but without evidence for Finnish ancestry.

Hereditary myopathy with lactic acidosis, succinate dehydrogenase and aconitase deficiency in northern Sweden: a genealogical study.

A hereditary myopathy with lactic acidosis during physical exercise, low physical work capacity, and paroxysmal myoglobinuria (HML), called "Myopathy with deficiency of succinate dehydrogenase and aconitase" (McKusick 255125) has been described in 19 members of nine families who lived in two geographically separate areas in northern Sweden. By using the unique Swedish historical archives, including Catechetical Meeting Records from a number of northern Swedish parishes, it has been possible to trace ancestors of the nine families including all known 19 cases back in time to some key couples, who lived up to 300 years ago (that is seven to ten generations). No common single couple or common links between families in the past was found in these registers as a support for a single or several mutations that had developed far back in time.

Outcome of pregnancy in women with myotonic dystrophy and analysis of CTG gene expansion.

Pregnancy outcome was investigated in 32 women with clinically obvious myotonic dystrophy. The results indicated that there are two groups of women, those whose children have the adult type of myotonic dystrophy and those whose children have the congenital type. The overall perinatal mortality was 14%.

Geographical distribution of haplotypes in Swedish families with Huntington's disease.

This study was planned to determine the number of origins of the mutation underlying Huntington's disease (HD) in Sweden. Haplotypes were constructed for 23 different HD families, using six different polymorphisms [(CCG)n, GT70, 674, BS1, E2 and 4.2], including two within the gene.
