ATXN10 and Friedreich ataxia: Among them, we could identify varying degree of polymorphism in RFC1, associated with CANVAS; DAB1, where we identified a known expansion of the motif AAAAT but not the pathogenic ATTTC, which is associated with SCA37; ATXN10, where we detected an expansion of the motif ATTCT in 12 individuals, all from Central and South America (where SCA10 is predominantly found), all in the intermediate range (30-799 copies); FXN, where we found short expansions of the GAA motif in 59 individuals (long expansions, usually > 2kb, are known to cause Friedreich’s Ataxia).
