Background. Abnormal expansion of the CAG microsatellite in the HTT gene is the cause of Huntington's disease (HD), but the potential role of the CCG polymorphism (adjacent to CAG microsatellite) as a modifying factor of this disease has not yet been resolved. Aim. To determine the association between the CCG polymorphism and the expansion of the CAG microsatellite in the HTT gene of a Peruvian population treated at the Instituto Nacional de Ciencias Neurológicas during the period 2000-2013. Methods. CCG polymorphism and CAG microsatellite were analyzed in 63 unrelated expanded alleles (EA) of mestizo ethnic origin and in 218 unrelated control alleles (CA) belonging to two different ethnic groups from Peru (132 alleles of mestizo origin and 86 of Amerindian origin). Results. In the EA, three types of CCG repeats were identified: (CCG)4, (CCG)7, and (CCG)10; the (CCG)7 repeat was the most frequent (84.13%). In CA, (CCG)7, (CCG)9, (CCG)10, and (CCG)11 repeats were identified, the (CCG)7 was the most frequent in both populations (65.91% in alleles of mestizo and 59.30% of Amerindian origin). In CA and EA, haplogroups A and B were associated with the (CCG)7 repeat. Haplogroup C was associated with the (CCG)9, (CCG)10, and (CCG)11 repeats. Conclusions. The CCG polymorphism is associated with the expansion of the CAG microsatellite in the HTT gene.
