ChAS software directly indicates the origin of the isodisomic UPD. After comparing the genotyping results between the fetus and his parents, ChAS software clearly indicated that the UPD of chromosome 4 in the fetus originated from the mother. At position chr4:3,418,266, the genotyping was BB, AA and AB in the fetus, his father and his mother, respectively, which indicates that the B allele in the fetus was duplicated from his mother. There are many different alleles that can be used to identify the origin of chromosome 4 in the fetus (red arrows)
