Umbilical cord blood biochemistry demonstrated fetal anemia, coagulation disorders, and abnormal liver and kidney function. Autopsy confirmed fetal hydrops and associated anomalies. A novel compound heterozygous mutation comprising the missense variant c.754T&amp;gt;C (p.Ser252Pro) and a partial exonic deletion (deletion of exons 1\u20132) in the ALG8 gene was identified in fetus P2.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>This study represents the first prenatal diagnosis of ALG8-CDG, comprehensively delineating the prenatal phenotypic spectrum.
