## Computational & population evidence {#evidence}

**Concordance:** Mixed / partial computational evidence (see below).

- **Missense predictors (AlphaMissense/REVEL/SaProt) do not apply** to this variant type — they score amino-acid substitutions only. For non-missense variants the computational signal comes from conservation (below), not from a missing predictor score.
- Conservation: phyloP -1.779, GERP -3.23 — not a conserved position (phyloP < 0.1, ACGS BP7 cut)
- CADD: **PHRED 0.558**. No single ClinGen-calibrated threshold exists and the expert panels that use CADD disagree — GUCY2D/AIPL1 require ≥ 20.0 for an untranslated-region variant, ABCA4 ≥ 28.1 for a synonymous or indel variant, the Pulmonary Hypertension panel imports Pejaver 2022's missense-calibrated numbers, and the Antibody Deficiencies panel declines CADD entirely for PIK3CD. CADD v1.7 also incorporates Zoonomia phyloP, so it partly re-expresses the conservation above. *Descriptive; no threshold applied.*
- SpliceAI: **below the reporting threshold**. This position is scored for a different substitution (A>C, Δ0.78 donor gain), so this allele was evaluated and its deltas all fell under Δ0.2 — a prediction of no splicing effect for this allele, not a gap in our data. *No ACMG code assigned.*
- Population frequency (gnomAD v4.1): grpmax **0.213%** (nfe) · FAF95 0.206% · FAF99 0.203% · 2,498/1,172,734 in the highest group · 2,662/1,599,040 alleles overall — rare (popmax 0.213%, nfe).

| Ancestry group | Allele frequency | 1 in |
| --- | --- | --- |
| European (non-Finnish) (grpmax) | 0.213% | 469 |
| Remaining individuals (not grpmax-eligible) | 0.105% | 952 |
| Finnish (not grpmax-eligible) | 0.0536% | 1,864 |
| African / African-American | 0.0535% | 1,870 |
| Admixed American | 0.0405% | 2,468 |
| Ashkenazi Jewish (not grpmax-eligible) | 0.00698% | 14,326 |

*Computational predictors are not independent (ClinGen Variant Classification guidance): AlphaMissense (Cheng et al. 2023) carries the ACMG weight for missense and conservation (phyloP/GERP/phastCons) for non-missense; REVEL (Pejaver-2022 calibrated strength bands) and SaProt (Su et al. 2023, structure-aware, ClinVar-independent protein language model, raw LLR) are shown as orthogonal agreement signals, not additive. For frequency, the gnomAD v4.1 grpmax filtering allele frequency (FAF95) is ClinGen's designated BA1/BS1 input (gnomAD v4 guidance v3.0, June 2025); BA1/BS1 thresholds are disease-specific, not a blanket 5%. Predictions, not a clinical determination.*

## Gene constraint & dosage {#gene-context}

**SCRIB** population constraint: LOEUF 0.684, pLI 8.3323e-12, missense-Z -3.2663. *Lower LOEUF and higher pLI indicate a gene that tolerates loss-of-function poorly; ClinGen dosage is the curated haploinsufficiency call.*

## Protein context {#protein}

Residue **889** lies in the pdz 2 domain; the 'interaction with arhgef7' region; the 'required for interaction with vim' region.

AlphaFold model confidence (whole protein): pLDDT 52.33, 0% of residues very-high.

**42 experimental structure(s)** (PDB): [9KFM](https://www.rcsb.org/structure/9KFM), [9KFN](https://www.rcsb.org/structure/9KFN), [9KFO](https://www.rcsb.org/structure/9KFO), [9KQS](https://www.rcsb.org/structure/9KQS), [9UK1](https://www.rcsb.org/structure/9UK1), [9UK3](https://www.rcsb.org/structure/9UK3) — incl. mutant structure 6EEY.

## What this gene does {#gene-function}

*Describes the biological roles of SCRIB (the gene this variant disrupts) — not effects measured for this specific variant. A damaging variant is expected to affect these functions and pathways; the degree depends on the variant.*
