Opportunity units

Single exon

5' ─ E1 ─ [E2] ─ E3 ─ 3'

Coverage asks what fraction of gene-level ClinVar P/LP records falls in one exon.

Adjacent exon block

5' ─ E1 ─ [E2 ─ E3 ─ E4] ─ E5 ─ 3'

Coverage asks what fraction falls in a local block of neighboring exons.

Downstream-CDS

5' ─ E1 | [downstream coding payload] ─ 3' boundary

Coverage asks what fraction lies downstream of a transcript boundary. Early boundaries can make coverage high, so read this with donor payload and context caveats.

Payload bins

BinMeaning
≤5 kbcompact payload descriptor
5–20 kbmoderate payload burden
>20 kblarge-payload / donor/payload-burden caveat
>50 kbultra-large burden

Payload bins are interpretation bins, not feasibility cutoffs.
