In this article, there were two annotation mistakes about the precise deletion position in COL4A3 and COL4A4 mutations in ARAS patients (summarized in Figure 2E). This was caused by a bug in the old version (v3.4) of Variant Caller for Ion Torrent. The variant in family AP5 should be described as ‘chr2:227942771delG’, instead of ‘chr:227942770delG’, in the COL4A4 gene. The variant identified in family AP1 should be described as ‘chr2:228172490delA’, instead of ‘chr:228172489delA’, in the COL4A3 gene.
