Severe neck pain and sudden unexpected death may occur due to skeletal abnormalities at the cranio-cervical junction or cervical region and is associated with neurological signs and sym...

In 1980, polymorphic variance in the human genomewasused to generate a first, physical map allowing monogenic traits to be traced to certain chromosomal regions. Due to the recognition of fragment length polymorphisms (microsatellite markers) with several different alleles at the same chromosomal locus, single nucleotide polymorphisms (SNP) became neglected in this instance for a long time. The...
