ADD3 and breast angiosarcoma: Interestingly, a long non-coding RNA ADD3-antisense 1 (lncRNA-ADD3-AS1), situated in locus 10q25.1, with the 5’-end overlapping with the ADD3 gene, was shown to increase susceptibility to BA, which suggested that the lncRNA-ADD3-AS1 transcript played an additive role in the pathogenesis of the disease [25].
