The variant received -12 classification points (ACMG Germline Pathogenicity v2019). BA1BP4_Strong

The NM_001367975.1(BTG4):c.-27+341A>G variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.321 (AC=48,754) in the gnomAD database across 152,096 control chromosomes, including 7,984 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.359. 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.

Genes affected
BTG4 (HGNC:13862): (BTG anti-proliferation factor 4) The protein encoded by this gene is a member of the BTG/Tob family. This family has structurally related proteins that appear to have antiproliferative properties. This encoded protein can induce G1 arrest in the cell cycle. [provided by RefSeq, Jul 2008]

Classification according to ACMG Germline Pathogenicity v2019

Classification was made for transcript:

Our verdict: Benign. The variant received -12 points.

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 = 0.3586 — exceeds 5%% threshold (BA1 applied)
