<abstract xmlns="http://www.w3.org/1999/xhtml">Initial Rh phenotyping of a man with hemolytic anemia, his wife, and son appeared to exclude paternity. No exclusion was found in other blood groups or in the human leukocyte antigen (HLA) system; excluding Rh, the paternity index was 98.58 percent. Samples from these three family members, and two other family members, were tested with additional Rh antisera. The results indicated that the propositus has an Rhmod phenotype with expression of c, weak e, and very weak D, E, and G antigens. To support this hypothesis, DNA analysis of the <italic>RHD</italic> and <italic>RHCE</italic> genes was performed on the five family members. Polymerase chain reaction (PCR) products from exons 2 and 5 were analyzed by denaturing gradient gel electrophoresis (DGGE).
