SETDB2 (SET domain, bifurcated 2), LOC102187058 (proteasome subunit beta type-6 pseudogene) and LOC102191519 (protocadherin gamma-C4), colocalized with LF unique candidate genes CYM, PROK1, RAB22A (RAB22A, member RAS oncogene family) and MROH6 (maestro heat-like repeat family member 6), and 4 SNPs in the HF group colocalized in the shared candidate genes CDH26 (cadherin 26) and EML1 (echinoderm microtubule associated protein like 1), 1 SNPs in the LF groups colocalized in the shared candidate gene CD3D (CD3d molecule, delta) (Fig. 6; Table 5; Table S3). Here, CMA1 is linked to hydrops fetalis.
