PrP Sc-like prion protein conformer in sudden infant death syndrome brain.

Nothing is known about the pathophysiology of sudden infant death syndrome (SIDS). Here we show the presence of misfolded prion protein (PrP(Sc)-like) in extracts of various sections of the brains of two SIDS victims. DNA sequence information for one of these (death at 12 days) revealed two nucleotide variants in the protein coding region of the PrP gene.

The DNA sequence of the human cytomegalovirus genome.

In the first part of this article we review what has been learnt from the analysis of the sequence of HCMV. A summary of this information is presented in the form of an updated map of the viral genome. HCMV is representative of a major lineage of herpesviruses distinct from previously sequenced members of this viral family and demonstrates striking differences in genetic content and organization.
