abstract = {DNA damage and unrepaired or insufficiently repaired DNA
double-strand breaks as well as telomere shortening
contribute to the formation of structural chromosomal
aberrations (CAs). Non-specific CAs have been used in the
monitoring of individuals exposed to potential carcinogenic
chemicals and radiation. The frequency of CAs in peripheral
blood lymphocytes (PBLs) has been associated with cancer
risk and the association has also been found in incident
cancer patients. CAs include chromosome-type aberrations
(CSAs) and chromatid-type aberrations (CTAs) and their sum
CAtot. In the present study, we used data from our published
genome-wide association studies (GWASs) and extracted the
results for 153 DNA repair genes for 607 persons who had
occupational exposure to diverse harmful
substances/radiation and/or personal exposure to tobacco
smoking. The analyses were conducted using linear and
logistic regression models to study the association of DNA
repair gene polymorphisms with CAs. Considering an arbitrary
cutoff level of 5 × 10-3, 14 loci passed the threshold, and
included 7 repair pathways for CTA, 4 for CSA, and 3 for
CAtot; 10 SNPs were eQTLs influencing the expression of the
target repair gene. For the base excision repair pathway,
the implicated genes PARP1 and PARP2 encode
poly(ADP-ribosyl) transferases with multiple regulatory
functions. PARP1 and PARP2 have an important role in
maintaining genome stability through diverse mechanisms.
Other candidate genes with known roles for CSAs included
GTF2H (general transcription factor IIH subunits 4 and 5),
Fanconi anemia pathway genes, and PMS2, a mismatch repair
gene. The present results suggest pathways with mechanistic
rationale for the formation of CAs and emphasize the need to
further develop techniques for measuring individual
sensitivity to genotoxic exposure.},
