Genes affected

CARD8 (HGNC:17057): (caspase recruitment domain family member 8) The protein encoded by this gene belongs to the caspase recruitment domain (CARD)-containing family of proteins, which are involved in pathways leading to activation of caspases or nuclear factor kappa-B (NFKB). This protein may be a component of the inflammasome, a protein complex that plays a role in the activation of proinflammatory caspases. It is thought that this protein acts as an adaptor molecule that negatively regulates NFKB activation, CASP1-dependent IL1B secretion, and apoptosis. Polymorphisms in this gene may be associated with a susceptibility to rheumatoid arthritis. Alternatively spliced transcript variants have been described for this gene.

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0034770072).
• BP6: Variant 19-48211939-T-C is Benign according to our data. Variant chr19-48211939-T-C is described in ClinVar as [Benign]. Clinvar id is 1169236.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr19-48211939-T-C is described in Lovd as [Benign].
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0181 (2763/152278) while in subpopulation NFE AF= 0.0282 (1917/68018). AF 95% confidence interval is 0.0271. There are 26 homozygotes in gnomad4. There are 1326 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 2763 AD gene.
