These 19 more variable repeat loci (RAI1, UMAD1, GLS, HTR7P1, CNKSR2, MAML3, MED15, MLLT3, USF3, MEF2A, MIR205HG, NCOR2, RPL14, JPH3, MAB21L1, ANKUB1, ERF, GIPC1, and EP400) were further screened in our ataxia patient cohort to identify any length variation that might be pathogenic (Fig. 3). The gene discussed is GIPC1; the disease is Ataxia.
