In SP vs C, a majority (1543/2319 or 67%) of the DEGs were also differentially expressed in CP vs C, including known CP signature genes such as S100A7A, SPRR2B, IL36A/G, IL17D/F/RD/RE and SERPINB4. Keratin (KRT-) and keratin-associated protein (KRTAP-) family genes were also highly expressed in SP and in many cases, DE between SP and C, much more so than in CP or HF. This evidence concerns the gene S100A7A and hydrops fetalis.
