The NM_024675.4(PALB2):c.3484G>C (p.Val1162Leu) variant causes a missense 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 (REVEL) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain Significance (★). Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.V1162M: Uncertain_significance (ClinVar VariationId 410133, 2 stars); p.V1162= (synonymous): Benign/Likely_benign (ClinVar VariationId 823828, 2 stars)

Genes affected

PALB2 (HGNC:26144): (partner and localizer of BRCA2) This gene encodes a protein that may function in tumor suppression. This protein binds to and colocalizes with the breast cancer 2 early onset protein (BRCA2) in nuclear foci and likely permits the stable intranuclear localization and accumulation of BRCA2.

Classification according to ACMG Germline Pathogenicity v2019

Specifications for PALB2 are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Our verdict: Uncertain_significance. The variant received 0 points.

• PM2: Absent from gnomAD (AD/XL gene) — PM2; Absent from gnomAD at well-covered site (MOI: AD+AR) (base 0.0001, raised to 0.000208 by highest known P/LP ClinVar AF 0.000208) — PM2 moderate.
• BP4: Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Moderate).
