Long-chain perfluoroalkyl substance. Immune, developmental, and metabolic signals are seed hypotheses. They are not summed into one hazard number.

Flags: environmental chemical · legacy

Phase-1 numbers are seed hypotheses. They are not curated consensus, not a toxicity total, and not a statement of human risk. Association is not written as causation.

+3

Headline +3 is the strongest independent cluster (GONADAL_FUNCTION: Fertility). Other clusters and child mechanisms were not added. Human relevance is the relevance of the headline cluster, not the maximum relevance anywhere in the domain, and it is not multiplied into the score. No curated scientific findings are linked yet. The number is a seed assessment, not a literature count. Direction DISRUPTIVE. Confidence LOW. Human relevance H2. Supporting findings 0. Contradictory findings 0. Curation SEED_HYPOTHESIS.
