Genes affected

BCL10 (HGNC:989): (BCL10 immune signaling adaptor) This gene was identified by its translocation in a case of mucosa-associated lymphoid tissue (MALT) lymphoma. The protein encoded by this gene contains a caspase recruitment domain (CARD), and has been shown to induce apoptosis and to activate NF-kappaB. This protein is reported to interact with other CARD domain containing proteins including CARD9, 10, 11 and 14, which are thought to function as upstream regulators in NF-kappaB signaling. This protein is found to form a complex with MALT1, a protein encoded by another gene known to be translocated in MALT lymphoma. MALT1 and this protein are thought to synergize in the activation of NF-kappaB, and the deregulation of either of them may contribute to the same pathogenetic process that leads to the malignancy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2016]

BCL10 (HGNC:):

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most 50 bp of the penultimate exon, not predicted to undergo nonsense mediated mRNA decay. There are 9 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-85270792-G-A is Pathogenic according to our data. Variant chr1-85270792-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 6266.Status of the report is criteria_provided_single_submitter, 1 stars.

This sequence change creates a premature translational stop signal (p.Arg58*) in the BCL10 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BCL10 are known to be pathogenic (PMID: 25365219, 32008135). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with BCL10-related conditions. ClinVar contains an entry for this variant (Variation ID: 6266). For these reasons, this variant has been classified as Pathogenic. -
