Diagnostics at the genetic level: Finding and Characterization of DNA-Sequencevariants

... there is no better way to advance the proper practice of medicine than to give our minds to the discovery of the usual laws of nature by careful investigation of cases of rarer forms of diseases. William Harvey (1578–1657) in a letter to the physician Jan Vlackfeld Haarlem, Netherlands, April 24 th, 1657 cf. Groft SC and Posada M (2010) in: Rare Disease Epidemiology, chpt. 1 Adv. Exp. Med. Biol. Vol. 686, pp. 3 –14

THEMED ARTICLE Review The advent of next-generation sequencing technologies has revolutionized the study of genetic variation in the human genome. … and variants detected in noncoding regions remain largely uninterpretable. … … variants detected in noncoding regions remain largely uninterpretable.

ACMG recommendations for standards for interpretation and reporting of sequence variations: Revisions 2007 Genetics IN Medicine, April 2008 Vol. 10 No. 4, Sequence variation is previously reported and is a recognized cause of the disorder 2. Sequence variation is previously unreported and is of the type which is expected to cause the disorder 3. Sequence variation is previously unreported and is of the type which may or may not be causative of the disorder 4. Sequence variation is previously unreported and is probably not causative of disease 5. Sequence variation is previously reported and is a recognized neutral variant 6. Sequence variation is not known or expected to be causative of disease, but is found to be associated with a clinical presentation

Things should be made as simple as possible, but not simpler.
