Claims
Breed: Weimaraner (Dog)Disorder:Clin feat: Christen et al. (2023): Four Weimaraner dogs (3 males and 1 female) from three different litters were presented for episodes of abnormal gait characterized by increased muscle contractions (dystonia), ataxia, and hypermetria, leading to occasional collapse. Kyphosis and low head carriage were also consistent features... . ... The age of onset was 3 to 7 months. Increased emotional arousal or exercise was reported to trigger the abnormal episodes, which could occur multiple times daily for 5 to 15 minutes. Two dogs displayed intermittent anisocoria associated with the episodes. Resting physical and neurological examinations were unremarkable in all cases, although the reported abnormalities were elicited by short periods of exercise in 3 dogs. Results of diagnostic investigations, including hematology, biochemistry, urine organic acids, lactate and pyruvate levels, enzymatic testing for storage diseases, acetylcholine receptor antibodies, muscle and nerve biopsies, MRI (brain and spinal cord), cerebrospinal fluid analysis, and electrophysiology, were mainly unremarkableDefect: yes

- Gene: Entrez Gene ID 388254795 (no symbol in OMIA GeneSynonym) — OMIA Phene_Gene
- OMIA molecular-genetics note: Christen et al. (2023): "Whole genome sequencing revealed a private frameshift variant in the TNR (tenascin-R) gene in an affected dog, XM_038542431.1:c.831dupC, which is predicted to truncate more than 75% of the open read frame. Genotypes in a cohort of 4 affected and 70 unaffected Weimaraners showed perfect association with the disease phenotype."
