A gap names a measurement, dataset, model or control that is missing, and links to the evidence records that say so. A gap is marked addressed only with the publication or record that addresses it. Gaps keep hypotheses honest about what remains open.

Missing measurementMeasurement proposed
Checkpoint competence and chromosome segregation have not been measured for either variant
Mitotic-arrest duration under spindle challenge is a checkpoint control, not chromosome-segregation fidelity in unperturbed divisions, and the published control variant (D137R) is not N1002K. Both endpoints must be measured separately for L737* and N1002K.

L737* NMD susceptibility is predicted, not measured
Whether the L737* transcript is degraded by nonsense-mediated decay in cells carrying the variant has not been measured; the case treats it as a prediction. A related 731X construct motivates testing truncated-protein function once NMD is bypassed, but the exact L737* experiment has not been performed.

Missing measurementMeasurement proposed
N1002K stability and residual function are unresolved
No exact-N1002K functional experiment was located. I909T and L1012P are comparator variants, not substitutes; equal abundance is not universally sufficient for rescue. The proposed measurement compares WT, N1002K and L1012P at matched abundance in one depletion-replacement system.

BioLab is the biomedical research area of Stackfire Labs: research cases built around open evidence, reproducible reanalyses and an explicit record of what remains unresolved. It organizes evidence and proposes experiments; it does not run patient experiments or recommend treatments.
Two germline BUB1B variants in mosaic variegated aneuploidy raise separate questions: L737* is an RNA and translation question, N1002K a protein stability and function question. The case records reanalyses and evidence audits, an October 24, 2026 robustness audit and a candidate decision matrix. No exact-genotype pharmacological rescue is established; wet-lab validation remains future work.
A shared research library of publications kept as references, not copies. Every entry links to its original source and records which public bibliographic services supplied its metadata and when. Reading states and collections are bibliographic organization, never scientific validation.
The graph connects a case to its variants, processes, evidence records, publications and hypotheses. Solid lines are documented connections; dashed lines are hypotheses under review. A connection says that a source or record links two items: it is not evidence of causation or efficacy. Every view also has a list alternative.
A research trail is an ordered reading of the evidence, step by step. Hypotheses are statements under research with the evidence that informs or limits them; none is marked validated. Evidence gaps name what has not been measured or located. All of them link to existing records and publications instead of copying them.
The auditable record of the MVA reanalyses with their execution records and downloads, and a Protein Structure Explorer of the predicted BUBR1 model. Tools marked Planned are not built yet. Reanalyses of public processed data and predicted structures are not biological experiments.
No. BioLab is research context, not a clinical diagnostic report or a treatment recommendation. Drug candidates are research hypotheses with explicit gates, not proven treatments. Questions about a person’s care belong with their clinical team.
