Mendelian trait/disorder: unknown

Considered a defect: yes

Cross-species summary: A site on a chromosome that does not stain, at which a break in the chromosome often occurs. In cultured cells, chromosomal breakage at fragile sites can be induced by the addition of caffeine or aphidicolon or bromodeoxyuridine to the culture medium. In humans, fragile sites are sometimes associated with tandem repeats of three nucleotides (triplet microsatellites) which, if the number of repeats increases, can cause inherited disorders. No such examples have yet been documented in domesticated animals.

Species-specific description: Some fragile sites in pigs correspond to breakpoints in known reciprocal translocations (Yang and Long, 1993).
