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]

Uncertain significance, no assertion criteria provided	clinical testing	Genetic Services Laboratory, University of Chicago	Aug 22, 2022	DNA sequence analysis of the CARD11 gene demonstrated a sequence change, c.2395G>A, in exon 18 that results in an amino acid change, p.Asp799Asn. This sequence change does not appear to have been previously described in individuals with CARD11-related disorders. This sequence change has been described in the gnomAD database in one individual in the East Asian subpopulation which corresponds to a population frequency of 0.0005% (dbSNP rs587778152). The p.Asp799Asn change affects a moderately conserved amino acid residue located in a domain of the CARD11 protein that is not known to be functional. In-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL) provide contradictory results for the p.Asp799Asn substitution. Due to insufficient evidences and the lack of functional studies, the clinical significance of the p.Asp799Asn change remains unknown at this time. -

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 799 of the CARD11 protein (p.Asp799Asn). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CARD11-related conditions. ClinVar contains an entry for this variant (Variation ID: 133798). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on CARD11 protein function. 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. -
