Cross-species summary: Spongiform encephalopathies are a class of fatal neurological diseases. Clinical signs are characteristic of a progressive degeneration of the central nervous system; they include pruritis, abnormalities of gait and recumbency. Death is inevitable. On post-mortem, brain histopathology shows a characteristic spongy appearance. The infectious agent is a modified form of a protein encoded by a gene in the host. The name given to this infectious particle is prion. The host gene is called the prion protein (PrP) gene, which is a normal part of the genome of mammals and chickens. Its polypeptide product, called cellular PrP(superscript C), is a naturally-occurring protein attached to the outer surface of neurones and some other cells. PrP(superscript C) appears to play a role in maintaining the Purkinje cells of the cerebellum, which are essential for balance and muscular function. The infectious agent, called scrapie PrP(superscript Sc), is a modifed form of PrP(superscript C), where the modifications involve glycosylation and the creation of intra-strand di-sulphide bonds. It is important to realise that these modifications involve no change in amino acid sequence. When PrP(superscript Sc) molecules enter a previously uninfected host, they convert the naturally occurring PrP(superscript C) molecules, produced by the host gene, into infectious PrP(superscript Sc) particles, which ultimately cause clinical signs in that animal, and which can spread to other animals, both horizontally (by infection) and vertically (by maternal transmission).

Species-specific description: Pirisinu et al. (2022): Nor98/atypical scrapie (AS) is a prion disease of sheep and goats ... . At variance with classical scrapie (CS), AS is considered poorly contagious and is supposed to be spontaneous in origin. The zoonotic potential of AS, its strain variability and the relationships with the more contagious CS strains remain largely unknown. We characterized AS isolates from sheep and goats by transmission ... in two genetic lines of bank voles, carrying either methionine (BvM) or isoleucine (BvI) at PrP residue 109. ... In bank voles, we found that the M109I polymorphism dictates the susceptibility to AS. BvI were susceptible and faithfully reproduced the AS strain, while the transmission in BvM was highly inefficient and was characterized by a conformational change towards a CS-like prion strain. Sub-passaging experiments revealed that the main strain component of AS is accompanied by minor CS-like strain components, which can be positively selected during replication in both AS-resistant or AS-susceptible animals."

Variants

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.

Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
