  1. Description of nucleotide variations is in accordance with BIC nomenclature* (DNA variants are numerated according to NCBI reference sequence HSU14680 for mRNA of BRCA1; the first nucleotide of mRNA is numerated as 1) or HGVS nomenclature** (DNA variants are numerated according to NCBI reference sequence NM_007294.2 for BRCA1; the first nucleotide of the start codon ATG is numerated as 1). UV- unclassified variant.
