Expression responses of the lymphangiogenesis pathway in chylothorax fetuses.

Ind-B and Ind-A, pleural versus ascitic fluids in the index hydropic case with an ITGA9 p.G404S mutation before (Ind-B) and after (Ind-A) OK-432 treatment, respectively. FC-r and NFC-r, pleural versus ascitic fluids in hydropic cases with and without FC, respectively; both cases lacked mutations in the ITGA9, FOXC2, PTPN11, and VEGFR3 genes.
