Genes affected

CARD14 (HGNC:16446): (caspase recruitment domain family member 14) This gene encodes a caspase recruitment domain-containing protein that is a member of the membrane-associated guanylate kinase (MAGUK) family of proteins. Members of this protein family are scaffold proteins that are involved in a diverse array of cellular processes including cellular adhesion, signal transduction and cell polarity control. This protein has been shown to specifically interact with BCL10, a protein known to function as a positive regulator of cell apoptosis and NF-kappaB activation. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Apr 2012]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The variant is not observed in the gnomAD v2.1.1 dataset. Intron variant. In silico tools predict the variant to alter splicing and produce an abnormal transcript (SpliceAI: 0.92). The variant has been reported to be associated with CARD14 related disorder (ClinVar ID: VCV000684674 / PMID: 29477734). However, the evidence of pathogenicity is insufficient at this time. Therefore, this variant is classified as Uncertain significance according to the recommendation of ACMG/AMP guideline. -
