Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1 PM2 PM5 PP2 PP3_Strong

The NM_032415.7(CARD11):​c.89G>A​(p.Arg30Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,876 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R30G) has been classified as Likely pathogenic.

Genes affected

CARD11 (HGNC:16393): (caspase recruitment domain family member 11) The protein encoded by this gene belongs to the membrane-associated guanylate kinase (MAGUK) family, a class of proteins that functions as molecular scaffolds for the assembly of multiprotein complexes at specialized regions of the plasma membrane. This protein is also a member of the CARD protein family, which is defined by carrying a characteristic caspase-associated recruitment domain (CARD). This protein has a domain structure similar to that of CARD14 protein. The CARD domains of both proteins have been shown to specifically interact with BCL10, a protein known to function as a positive regulator of cell apoptosis and NF-kappaB activation. When expressed in cells, this protein activated NF-kappaB and induced the phosphorylation of BCL10. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PM1: In a domain CARD (size 92) in uniprot entity CAR11_HUMAN there are 12 pathogenic changes around while only 0 benign (100%) in NM_032415.7
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr7-2947707-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 473938.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), CARD11. . Gene score misZ 3.5439 (greater than the threshold 3.09). Trascript score misZ 3.7177 (greater than threshold 3.09). GenCC has associacion of gene with BENTA disease, immunodeficiency 11b with atopic dermatitis, severe combined immunodeficiency due to CARD11 deficiency.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.945

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant disrupts the p.Arg30 amino acid residue in CARD11. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 28826773, 30170123). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Experimental studies have shown that this missense change affects CARD11 function (PMID: 30170123). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 473939). This missense change has been observed in individual(s) with CARD11-related immunodeficiency (PMID: 30170123). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 30 of the CARD11 protein (p.Arg30Gln). -
