Genetic analysis revealed that she carried a homozygous mutation (p.Gly17Glyfs77∗) in the KRT18 gene (Fig. 2) that has been determined to be related to BA.[7] The p.Gly17Glyfs77∗ mutation is a new mutation that has not been published on the SNP and ClinVar database. This evidence concerns the gene KRT18 and breast angiosarcoma.
