OMIA:000515-9823 : Cardiomyopathy, hypertrophic in Sus scrofa
Categories: Cardiovascular system phene
Links to MONDO diseases: No links.
Mendelian trait/disorder: unknown
Considered a defect: yes
Cross-species summary: Increase in volume of the muscle tissue of the heart, due to an increase in the size of muscle cells, primarily in the left ventricle and ventricular septum.
Species-specific description: A hypertrophic cardiomyopathy (HCM) strain of pigs has been developed by selection (Huang et al., 1996).
Montag et al. (2018) produced affected pigs via a knock-in of the pig orthologue of a causative mutation (R723G in the MYH7 gene) in humans. This is a genetically-modified organism (GMO).
Inheritance: familial, multifactorial, with a moderate heritability (around 30%)
Molecular basis: Montag et al. (2018) created pigs affected with this disorder using "TALEN-mediated genome editing and successfully introduced the HCM-point mutation R723G into the MYH7 gene of porcine fibroblasts and subsequently cloned pigs that were heterozygous for the [human] HCM-mutation R723G . . . (c.2223C > G, NM_000257)". The authors introduced "the orthologous point mutation (c.2167C > G, NM_213855) in the genome of German Landrace pigs via TALEN based genome editing", thus producing a "knock-in" mutation.
