OMIA:001472-9823 : Neuronal ceroid lipofuscinosis, 2 in Sus scrofa (pig)
Links to MONDO diseases:
Mendelian trait/disorder: yes
Mode of inheritance: Autosomal recessive
Considered a defect: yes
Key variant known: yes
Year key variant first reported: 2022
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).
Yucatan Miniature, United States of America (Pig) (VBO_0013234).

By default, variants are sorted chronologically by year of publication, to provide a historical perspective.

order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column
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.
