Testing for cancer may soon be as simple as a pinprick. Researchers in the United Kingdom say they are developing a universal blood test to detect cancer. So far, the team from the University of Bradford has tested their lymphocyte genome sensitivity test on patients with melanoma, lung cancer and colon cancer.esting for cancer may soon be as simple as a pinprick.

Aicardi syndrome is a rare neurologic disorder first described by the French neurologist, Dr. Jean Aicardi, in 1965. It occurs almost exclusively in females (46,XX), however, it can also occur in males with Klinfelter Syndrome (47,XXY). A handful of reports in the literature exist of Aicardi syndrome in a normal male. Some of these reports have been disputed, and it is possible that these cases are caused by mosaic mutations of the Aicardi syndrome gene(s).
Most cases of Rett syndrome are caused by a mutation (change in the DNA) in the MECP2 gene, which is found on the X chromosome (one of the sex chromosomes), although mutations in other genes have been found in some cases where the symptoms don't quite follow the classic pattern described above.
