PTPRJ
Every register Sniff holds about PTPRJ, in one place, each strand cited to its source. This is a gene-level, model-of view of somatic cohort frequencies and human evidence, never a germline carrier status for an individual dog and never a per-dog prediction.
Somatic driver in canine cancer
The fraction of sequenced tumors somatically altered in PTPRJ, per cancer, from peer-reviewed cohorts. A cohort rate, not an individual-dog risk. Each cancer carries its cross-species concordance: whether the dog and human agree on this driver (commensurability-gated, INV-81).
The dog side carries more cited disease evidence. This is unaudited: it can mean the dog literature is genuinely ahead, or that our human ingestion is incomplete (the HEXA class). It is not a target until that is ruled out. Coverage, not importance. D = 1 dog vs H = 0 human cited disease channels.
