Figure 3From: Genetic characterization of Spinocerebellar ataxia 1 in a South Indian cohort Genotype-phenotype correlation among the SCA1 affected individuals. (a) Relationship between inheritance pattern and age of onset of the disease. Data was analyzed using one-way ANOVA with Dunnett’s multiple comparison test (*P = 0.0015 and **P = 0.005). (b) Inverse correlation of age of onset with respect to the CAG expansions in the symptomatic patients (r2 = 0.45 and P = 0.002), where individuals with maternally inherited alleles are represented as circles, paternally inherited alleles as squares and inheritance from both parents as triangles.Back to article page
