    Value of the loss of heterozygosity to BRCA1 variant classification. (PubMed, NPJ Breast Cancer)
    A relatively stable pattern of LOH (65.4%) of WT allele for PV tumors was observed, while the allelic balance (63%) or loss of variant allele (15%) was generally seen for carriers of BV. LOH data is a useful complementary argument for BRCA1 variant classification.
