Variant summary
The NM_001376571.1(MADD):c.3759+551T>C variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.262 (AC=39,783) in the gnomAD database across 152,038 control chromosomes, including 6,801 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.383. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Classification according to ACMG Germline Pathogenicity v2019
Our verdict: Benign. The variant received -12 points.
| Apply | Criterion Code & Title / Strength | Rationale / Clinical Context | |
|---|---|---|---|
| BP4Computational evidence suggests no impact | Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Strong). | ||
| BA1Stand-alone benign allele frequency (>5%) | GnomAD effective popmax AF >5% — BA1 stand-alone benign; GnomAD reliable popmax AF = 0.3832 — exceeds 5%% threshold (BA1 applied) |
