OMIA 002446-9615 : Alanine aminotransferase, reduced activty in Canis lupus familiaris

Possibly relevant human trait(s) and/or gene(s) (MIM number): 138200 (gene)

Mendelian trait/disorder: unknown

Considered a defect: unknown

Species-specific name: reduced ALT levels

Species-specific description: White et al. (2015): "From a cohort of dogs that had been previously genotyped on a semi-custom Illumina CanineHD array for various genome-wide association studies (GWAS) ..., we chose 353 clinically healthy, adult dogs for our analysis of clinical pathologic test results (14 hematological tests and 25 clinical chemistry tests). After correcting for age, body weight and sex, genetic associations were identified for amylase, segmented neutrophils, urea nitrogen, glucose, and mean corpuscular hemoglobin. Additionally, a strong genetic association (P = 8.1×10-13) was evident between a region of canine chromosome 13 (CFA13) and alanine aminotransferase (ALT), explaining 23% of the variation in ALT levels. This region of CFA13 encompasses the GPT gene that encodes the transferase. Dogs homozygous for the derived allele exhibit lower ALT activity, making increased ALT activity a less useful marker of hepatic injury in these individuals."
