Cross-species summary: One of several variants of neuronal ceroid lipofuscinosis (NCL) or Batten disease: CLN2; NCL2

Species-specific description: Swier et al. (2022) used recombinant AAV-mediated gene targeting to introduce a R208X mutation into the TPP1 gene in Yucatan miniswine to create a porcine model for CLN2 disease in humans. The authors "present comprehensive characterization showing behavioral, pathological, and visual phenotypes that recapitulate those seen in CLN2 patients." This study involves genetically modified organisms (GMO).

Genetic engineering: Yes - variants have been created artificially, e.g. by genetic engineering or gene editing
Have human generated variants been created, e.g. through genetic engineering and gene editing

Breed: Yucatan Miniature, United States of America (Pig) (VBO_0013234).
Breeds in which the phene has been documented. (If a likely causal variant has been documented for the phene, see the variant table breeds in which the variant has been reported).

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.
