CoGenEx-PM3 evidence

Evidence status is assigned at the PMID × variant level and should not be interpreted as a final variant-level pathogenicity classification.

Evidence status

Phase-unconfirmed biallelic evidence

Query-evidence confidence

High confidence

Exact query c.HGVS was found in retained evidence.

Phase-confirmed PM3 evidence

No

Phase-unconfirmed biallelic evidence

Yes

Other patient-level evidence

No

PM3 context

Possible compound heterozygous with Lys168Arg

PM3 evidence items

2

Allelic configuration type

Compound heterozygous candidate

Retained partner variants

• Lys168Arg

Partner variants are retained structured tokens from CoGenEx-PM3 evidence items. They are not transcript-normalized in this release.

Candidate context and target validation

Candidate context windows are places selected for audit because the query or its aliases may be relevant. They are not the same as a validated match to the target c.HGVS or p.HGVS expression.

Candidate context

Candidate context retained: 4 text windows and 2 table windows

Context status

Found in final retained audit context
