                  cancer 
        
      
         
          Genetics variation at the BRCA1 locus
          has been implicated in susceptibility to breast and (or)
          ovarian cancer in humans. The table lists 35 allelic variants
          so implicated, sorted by type of variant: these are Deletions and Insertions of 1 ~ 40 base
          pairs, non-synonymous
          substitutions leading to replacement of amino acids, and
          premature Terminations.
