OMIA 002084-9615 : Dyskinesia, paroxysmal, PIGN-related in Canis lupus familiaris

Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 614080 , 611147 , 118800

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2016

Molecular basis: By comparing the whole-genome sequence of two affected Soft-Coated Wheaten Terriers and "100 control canid whole genome sequences", Kolicheski et al. (2016) identified the likely causal mutation as a missense SNP (c.398C>T; p.T133I) in the PIGN gene.

Breed: Soft Coated Wheaten Terrier.

Associated gene:

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.
