The study by Horvath et al. [109], however, with data generated for 475 brain samples from various brain regions (i.e., the frontal, occipital and parietal lobes) of HD cases and controls reports 1467 CpGs, including CpGs in TMEM8A, IDE and GRIK2, to be significantly associated with HD in a meta‐analysis comprising the three brain regions analysed. Here, IDE is linked to Huntington disease.
