  1. Description of nucleotide variations is in accordance with BIC nomenclature* (DNA variants are numerated according to NCBI reference sequence U43746 for mRNA of BRCA2.; the first nucleotide of mRNA is numerated as 1) or HGVS nomenclature** (DNA variants are numerated according to NCBI reference sequence NM_000059.3 for BRCA2; the first nucleotide of the start codon ATG is numerated as 1).
