Classification according to ACMG Germline Pathogenicity v2019
Our verdict: Likely_benign. The variant received -2 points.
| Apply | Criterion Code & Title / Strength | Rationale / Clinical Context | |
|---|---|---|---|
| PM2Absent/extremely low in population databases | Absent from gnomAD (AD/XL gene) — PM2; Absent from gnomAD at well-covered site (MOI: AD+AR) (base 0.0001, raised to 0.00015 by highest known P/LP ClinVar AF 0.00015) — PM2 moderate. | ||
| BP4Computational evidence suggests no impact | Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); No splicing predictor data available.; Germline computational verdict: benign (Strong). |
