Chen et al reported that the incidence of mirror syndrome among 98,484 deliveries was 0.0162%, whereas that among patients with fetal hydrops was 23.2%.[5] They also noted that compared to the patients in the non-mirror syndrome group, the uric acid, lactate dehydrogenase, creatinine, and d-dimer levels were significantly, higher and the hemoglobin, hematocrit, platelet, and serum albumin values were lower in the mirror syndrome group.[5] In the present patient, the maternal symptoms along with fetal hydrops were edema, anemia, hypoalbuminemia, and a higher d-dimer level. The gene discussed is ALB; the disease is anemia (phenotype).
