Mendelian trait/disorder: yes

Mode of inheritance: Autosomal recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2007

Species-specific name: L-2-hydroxyglutaric aciduria

Species-specific symbol: L-2-HGA

Species-specific description: The first cases of this inborn error of metabolism in animals were reported by Abramson et al. (2001, 2003) [FN: 7 Oct 2003]

Molecular basis: Using a candidate gene strategy (based on the homologous disorder in humans), Penderis et al. (2007) sequenced "all 10 canine L2HGDH exons (with flanking intron regions) from the [Staffordshire bull terrier] affected dogs and two carrier dogs" and identified a causal mutation as "two single‐nucleotide substitutions separated by a single invariant T nucleotide in exon 10 (c[1297T→C; 1299c→t]; p[Leu433Pro; His434Tyr])". Sanchez-Masian et al. (2012) identified a different mutation in the same gene in a family of Yorkshire Terriers: a base substitution "at the translation initiation codon of the homolog canine L2HGDH gene was detected (c.1A>G; p.Met1?)". Farias et al. (2012) reported the same mutation in the same breed.

Breeds: Staffordshire Bull Terrier (Dog) (VBO_0201296), West Highland White Terrier (Dog) (VBO_0201415), Yorkshire Terrier (Dog) (VBO_0201448).

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.
