Interestingly, we detected HF cycling related genes such as WNT3A, HOXC13 and MSX2 which were located near the LNC_000972, LNC_000503 and LNC_000881 loci respectively (Table 1), suggesting that HF cycling may be regulated by the action of lncRNAs on neighboring protein-coding genes. This evidence concerns the gene MSX2 and hydrops fetalis.
