Hypotheses — Live Ranking

Eighteen therapeutic hypotheses for Misha’s DFNB16 compound-het (maternal E1659A + paternal 98kb Δ). Tiers update as proofs land. Every row links to the hypothesis hub, which carries phase history, active compute, and scripts.

Rubric

Axes 1–5: Mech (biology plausible), Deliv (cochlear delivery 3–5 yr), Misha-fit (compound het, age, OHC window).

Tier heuristic: min(Mech, Deliv, Misha-fit). S = top 5 active. A = backburner. B = watch. C = paused, needs external catalyst. D = killed.

Active register

All 18 numbered hypotheses. Auto-rendered from h{N}/index.md frontmatter. To change a row — edit the hub’s frontmatter (tier, mech, deliv, misha_fit, next_step), not this file.

Clinical plan for Misha per Misha Compound-Het Therapy Stack Model: pursue #1 (PC for maternal E1659A) + #3 (AAV for paternal null) in parallel. h01 is the only monotherapy route to NORMAL (≤ 25 dB ABR); stack provides redundancy and lower drug/AAV burden. Phase 5 MD on #1 is the critical-path compute that produces the f_PC parameter.

Decision gates

  • → D: mechanism falsified OR Misha-fit=1 OR delivery impossible 10 yr.
  • → C: no near-term computational step; log external catalyst.
  • → B: evidence neutral, shallow engagement.
  • → A: real progress possible, not highest-leverage today.
  • → S: top 5 max, advances Misha directly, actionable next step.

Literature-audit status

Per-hypothesis audit of parameter provenance against primary literature. Status (fixed / partial / deferred) is carried on each hub. See AGENTS §0c.

Legacy synthesis pages (pre-hub structure)

Older flat synthesis notes from 2026-04-21/22, superseded by the h{N}/index.md structure but kept for historical context:

  • delivery — sonoporation + LNP through round window (now in h04-mrna-lnp)
  • dual-vector — dual vs single vector math (now referenced by h03-mini-strc)
  • electrostatics — E1659A electrostatic analysis (reference tier)
  • immune — anti-AAV antibodies + re-dosing (supporting)
  • mini-strc — mini-STRC synthesis (now h03-mini-strc)
  • prime-editing — prime editing feasibility (now h07-prime-editing)
  • sonogenetics — sound-activated gene expression (now h12-sonogenetic)
