The genes from which these circRNAs originate (COL15A1, DOCK7, ADAMTS5, HADH, COL3A1, TGFBR3, ISM1, ARL13B, POSTN, KCTD9, KRT77, SEMA3C, CTNND1, DKK3, ZNF114, and FTO) are involved in the HF growth process [38,39,40,41,42,43,44,45,46,47,48,49,50,51,52]. This evidence concerns the gene HADH and hydrops fetalis.
