OMIA:001505-9940 : Neuronal ceroid lipofuscinosis, 10 in Ovis aries (sheep)
In other species: dog
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: 2000
Cross-species summary: One of several variants of neuronal ceroid lipofuscinosis (NCL) or Batten disease: CLN10; NCL10
Species-specific name: Congenital ovine NCL
Species-specific symbol: CONCL
History: The first report of this disorder was by Jarplid and Haltia (1993).
Molecular basis: By cloning and sequencing a very likely candidate gene (based on "a striking deficiency of [lysosomal enzyme] cathepsin D activity in the CONCL brain and liver compared with controls"), Tyynelä et al. (2000) reported the causal mutation in Swedish Landrace as being "A single nucleotide mutation [G->A] in the cathepsin D gene [CTSD] results in conversion of an active site aspartate to asparagine, leading to production of an enzymatically inactive but stable protein."
Note that NCBI Gene lists the CTSD gene in sheep as LOC443060.
Roslagsfår, Sweden (Sheep) (VBO_0016519).

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
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.
