The Biological Material Requirement Framework Genetic Information, Nutritional Substrates, Cellular Machinery, and the Development of Disease

Genetic information supplies the instructions for cellular function, but carrying out those instructions depends on biological materials (substrates, cofactors, transport systems, energy) and on intact cellular machinery. This dependence is established biochemistry. The BMRF does not propose it as a new finding. It proposes a structured method for investigating, case by case, how genetic capacity, material availability, processing capacity, regulatory state and biological timing interact to produce disease. The framework has three separate structures: - Mechanism profile: seven diagnostic questions (A to G), organised in two tiers. Primary mechanisms are A, C, D, E and F-function. Annotations are B, F-origin and G. The paper gives assignment rules, a profile template and worked profiles for phenylketonuria, cystathionine beta-synthase deficiency, methylmalonic acidemia and vitamin transporter defects. - Four analytical dimensions of material dependence: availability, accessibility, usability and regulation. - Five interacting variables: genetic capacity, material availability, processing capacity, regulatory state and biological timing. The paper also gives six testable hypotheses, a proposed methodology, and a pre-specified test of added value, with criteria for success, no added value and failure, plus an inter-rater reliability check. Four short illustrative cases (PARP1, GALT, GALT Q188R, OTC) demonstrate an evidence-recording convention. The biological claim, annotation level, evidence type and source-to-claim mapping are recorded as separate axes. These cases are interim and rest on database records and published papers as read on the dates stated. They present no new experimental data, and no item is promoted to verified status.
