There have been no reports of maternally transmitted alleles in this range producing offspring with affected alleles. The likelihood that transmission of an allele in this range will expand into an HD allele is dependent on several factors, including the sex of the transmitting individual, the size of the allele, the molecular configuration of the region surrounding the CAG repeat, and its haplotype. |
