CYSLTR1 and hydrops fetalis: In addition, given that Cysltr1 also fits most of the above-stated criteria (as (i) the expression profile of Cysltr1 also significantly correlates between bulk RNA sequencing and ddPCR, and (ii) Cysltr1 has already-approved antagonists that are currently indicated in the maintenance treatment of asthma), it was previously brought in touch with HF [22], Cysltr1 was also further characterized, the results of which are shown in the Supplementary Materials.
