Haplotype analysis for allele discrimination and tracing the origin of FMR1 fetal allele. Haplotype analysis using the polymorphic makers: DXS106, DXS8028, DXS998, FMR1: 146993469–147032647, DXS106, DXS8069, DXS8061, DXS1073 shows that the unstable allele transmitted from the grandmother to the mother and to her fetus.
