PIK3R1 and juvenile Huntington disease: With a stringent read filter of 30 reads per SNP and twofold AEI ratio, we detect 443 genes with likely AEI in any region such as Huntington’s Disease-associated: ELMO1, NTRK2, WNK1 and associated with Schizophrenia: NTRK2, PIK3R1 and RTN4. Table 4 contains the top 20 genes with AEI detected in any sample, sorted by magnitude of AEI ratios and by brain region.
