While we did not observe any effect of the CNV burden on age- and sex-corrected telomere length, the trait specifically associated with the BRCA1 cancer locus112 (MIM: 113705) (chr17: 41,197,733–41,258,551, βdup = 0.45 SD, p = 1.9 × 10−8), paralleling findings that long telomere-associated SNPs also associate with increased cancer risk.113. This evidence concerns the gene BRCA1 and cancer.
