Subacute sclerosing panencephalitis is typically characterized by alterations in the fusion protein cytoplasmic domain of the persisting measles virus

Virology. 1992 Jun;188(2):910-5. doi: 10.1016/0042-6822(92)90552-z.


Our recent extensive analysis of three cases of subacute sclerosing panencephalitis (SSPE) revealed intriguing genetic defects in the persisting measles virus (MV): the fusion (F) genes encoded truncated cytoplasmic F protein domains (Cattaneo et al., Virology 173, 415-425, 1989). Now this MV genomic region has been investigated in eight additional SSPE cases by PCR amplification, replacement cloning into a vector containing the F gene of a lytic MV, in vitro expression, and sequencing. In all cases at least part of the clones showed mutations leading to F protein truncations, elongation, or nonconservative amino acid replacements. It is proposed that alteration of the F protein cytoplasmic domain may play a critical role in the development of SSPE.
