C9orf78 and amyotrophic lateral sclerosis: The strongest overlapping signal was from our meta-analysis of AD, ALS, and PD GWAS, albeit non-significant: SNP rs112184630 (pMETA_GWAS = 5.91 × 10−7), located in chromosome 9q, which has been shown to be a blood eQTL for genes TOR1A (p = 6.74 × 10−16), FBP1 (p = 3.04 × 10−15), C9orf78 (p = 9.52 × 10−12) [43], and also PTGES (p = 7.92 × 10−6) [44].
