Claims

• Breed: Yorkshire Terrier (Dog)
• Disorder: L-2-hydroxyglutaric aciduria
• Mode of inheritance: Autosomal recessive
• Summary: The first cases of this inborn error of metabolism in animals were reported by Abramson et al. (2001, 2003) [FN: 7 Oct 2003]
• Defect: yes

Associated gene(s)

Derived from OMIA database dump (omia.xml, local); structured field, not verbatim prose. First-hand values below are verbatim substrings of the topic's pdf-raw/omia/<phene_id>.txt source file.

• Gene: Entrez Gene ID 26585840 (no symbol in OMIA GeneSynonym) — OMIA Phene_Gene
• OMIA molecular-genetics note: 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[Leu…
