Early: 20 up and 49 down sets qualify; late: 22 up and 21 down. That is 112 per condition.\n- Concatenated set files sha256 720d24b2…c13.\n\nGENE-SET ANALYSIS: magma --gene-results genes.genes.raw --set-annot <table>.sets.txt --model condition-hide=tested, one run per table. For APOE excluded, add --settings gene-exclude=apoe_region_genes.txt: the 69 NCBI37.3 genes overlapping chr19:44,409,039–46,412,650 (sha256 5c042491…5642). MAGMA's P is one-sided (beta>0). Bonferroni is over the 112 sets tested in each condition.\n\nRESULTS (magma_cps_sets.csv sha256 75033101…8d1f8d: one row per supertype × phase × direction × condition, with genes_in_set, genes_mapped, ngenes_magma, beta, se, one-sided p, Bonferroni p):\n- APOE included: 112 sets tested, 0 with Bonferroni p<0.05; 2 with nominal p<0.05.\n  - early Sst_22 down: 22 genes in set, 18 mapped; beta 0.491, SE 0.232, p=0.0170, adjusted p=1\n  - early Sst_20 up: 31 in set, 24 mapped; beta 0.328, SE 0.196, p=0.0475\n  - next: late Micro-PVM_2_3-SEAAD down (12 genes) p=0.060; early Pax6_3 up p=0.12 (Pax6_3 is from the included-condition top list, which the output shown earlier cut off; the rank is from the CSV)\n  - 64 of 112 betas are positive.\n- APOE excluded: 112 sets, 0 with Bonferroni p<0.05; 2 nominal.\n  - early Sst_20 up: beta 0.327, SE 0.194, p=0.0458\n  - early Sst_22 down: 0.400, SE 0.240, p=0.0479\n  - late Micro-PVM_2_3-SEAAD down: p=0.057\n  - Excluding the region removed 1–14 genes from 22 sets (ngenes_magma). One set, early L2/3 IT_3 down, fell to 9 genes and was still tested (p=0.19). Dropping it changes the denominator to 111 and nothing else.\nConclusion: at this set definition and threshold, AD GWAS signal is not detectably concentrated in genes that change with CPS in any MTG supertype, early or late. Many supertypes have too few q<0.05 genes to test: 112 of 556 possible sets qualified. So this is a null for the testable sets, not for every supertype.\nSupertype names come from the file names ('L2 3 IT' = L2/3 IT).\n\nCHECKS: gene-level Z for any gene can be compared against genes.genes.out (digest above). Set files are produced deterministically by pipeline.py.\n\nPRIOR ART, re-run 2026-09-30:\n- Europe PMC REST: (\"SEA-AD\" OR \"Seattle Alzheimer*\") AND (\"MAGMA\" OR \"GWAS\" OR \"heritability\" OR \"risk gene*\") AND (\"pseudoprogression\" OR \"pseudo-progression\" OR \"supertype*\"). 17 hits, all screened, including the July 2026 SEA-AD preprint and Genome Research 2026.
