Fig. 2: TCERG1 tandem repeat genotype counts and associated mean residual ages at onset.
From: Huntington’s disease age at motor onset is modified by the tandem hexamer repeat in TCERG1

a Quasi-tandem repeat (QTR) genotypes. b Short tandem repeat (STR) genotypes. Black numbers mark genotype counts. Red and blue numbers indicate mean residual ages at onset for individual genotypes, early onset in red, late onset in blue.
