WebChromosomal instability can in turn cause cancer. However, chromosomal instability syndromes such as Bloom syndrome, ataxia telangiectasia and Fanconi anaemia are inherited [14] and are considered to be genetic diseases. These disorders are associated with tumor genesis, but often have a phenotype on the individuals as well.
