The variant received -2 classification points (ACMG Germline Pathogenicity v2019). PM2BP4_Strong

The NM_000633.3(BCL2):c.586-52647A>T variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. 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

BCL2 (HGNC:990): (BCL2 apoptosis regulator) This gene encodes an integral outer mitochondrial membrane protein that blocks the apoptotic death of some cells such as lymphocytes. Constitutive expression of BCL2, such as in the case of translocation of BCL2 to Ig heavy chain locus, is thought to be the cause of follicular lymphoma. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

Classification according to ACMG Germline Pathogenicity v2019

Our verdict: Likely_benign. The variant received -2 points.

• PM2: Absent from gnomAD (AR/unknown gene) — PM2; Absent from gnomAD at well-covered site (MOI: unknown) (threshold 0.001) — PM2 moderate.
• BP4: Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Strong).
