We also performed qPCR to detect the expression of genes within the 2.5 Mb deletion in mice embryo hearts at E9.5, and found a relatively high expression level of Sox7, Eri1, Ppp1r3b, Msra, and Mfhas1. However, there was no report on the relationship between Eri1 or Mfhas1 and cardiovascular disease/development. This evidence concerns the gene ERI1 and cardiovascular disorder.
