phenotype affects entity aberrant DNA repair abnormal stress response abnormal DNA repair phenotypic_class Phenotype that is any abnormality in DNA repair (GO:0006281). 'DNA repair' is defined as: 'The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway.'
