Between 1934 and 1941, two internists from New York, Oppenheimer and Kugel, coined the term "Werner Syndrome," igniting a wave of interest and research on the disease. During that time, Agatson and Gartner suggested a possible link between Werners syndrome and cancer. However, it was not until 1966 that there was a general consensus on the autosomal recessive mode of inheritance for the syndrome. By 1981, geneticists had located the WRN gene on chromosome 8, leading to its cloning in 1996. This cloning of the WRN was significant because it revealed the predicted WRN protein was made from a family of DNA helicases. Prior to 1996, Werner syndrome was thought to be a model for accelerated aging. Since the discovery of the gene, it has become clear that the premature aging displayed in Werner syndrome is not the same, on a cellular level, as normal aging. The role of WRN in DNA repair and its exonuclease and helicase activities have been the subject of many studies in recent years.Since the initial discovery in 1904, several other cases of Werner syndrome have been recorded. Many of these cases have occurred in Japan, where a founder effect has caused a higher incidence rate than in other populations. The incidence rate of Werner syndrome in Japan is approximately 1 case per 100 thousand people (1:100,000), a large contrast with the rate of incidence for the rest of the world, which is between 1:1,000,000 and 1:10,000,000.
Treatment of Patau syndrome focuses on the particular physical problems with which each child is born. Many infants have difficulty surviving the first few days or weeks due to severe neurological problems or complex heart defects. Surgery may be necessary to repair heart defects or cleft lip and cleft palate. Physical, occupational, and speech therapy will help individuals with Patau syndrome reach their full developmental potential. Surviving children are described as happy and parents report that they enrich their lives. Prognosis
Approximately 90% of infants with Patau syndrome die within the first year of life. Those children who do survive past 1 year of life are typically severely disabled with intellectual disability, seizures, and psychomotor issues. Children with the mosaic variation are usually affected to a lesser extent. In a retrospective Canadian study of 174 children with trisomy 13, median survival time was 12.5 days. One and ten year survival was 19.8% and 12.9% respectively, including those who underwent aggressive surgical intervention. History
Trisomy 13 was first observed by Thomas Bartholin in 1657, but the chromosomal nature of the disease was ascertained by Dr. Klaus Patau and Dr. Eeva Therman in 1960. The disease is named in Pataus honor.In England and Wales during 2008–09, there were 172 diagnoses of Patau syndrome (trisomy 13), with 91% of diagnoses made prenatally. There were 111 elective abortions, 14 stillbirth/miscarriage/fetal deaths, 30 outcomes unknown, and 17 live births.
