The NM_001184900.3(CARD8):c.304T>A (p.Phe102Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The gene CARD8 is a tumor suppressor gene (CancerMine: 1 TSG, 1 oncogene, 1 driver citations). The gene CARD8 is a known oncogene (CancerMine: 1 TSG, 1 oncogene, 1 driver citations). The gene CARD8 is a cancer driver gene (CancerMine: 1 TSG, 1 oncogene, 1 driver citations). The variant allele was found at a cumulative frequency of 0.323 (AC=520,684) in the gnomAD database across 1,612,308 control chromosomes, including 86,121 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.478. In-silico predictor (REVEL) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (★★). The variant has been observed in cBioPortal in 7 samples across 5 studies and 5 cancer types; somatic enrichment level: SUPPORTING (Observed repeatedly in cBioPortal somatic datasets.). This exact variant is curated in the UniProt human variants database as Uncertain Significance, associated with Inflammatory bowel disease 30 (IBD30); it is also listed as a COSMIC curated somatic variant.

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.

Classification according to ACGS-UK Somatic Oncogenicity v2025

Classification was made for transcript:

Our verdict: Likely_benign. The variant received -4 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	O4Enriched in somatic variant database		Enriched in cBioPortal (pre-computed score ≥ 1.0) — Supporting (O4); cBioPortal: samples=7 | studies=5 | cancer types=5 | level=SUPPORTING | points=1.0 | reason: Observed repeatedly in cBioPortal somatic datasets.
	B1High frequency in general population		GnomAD effective popmax AF >1% — B1 stand-alone benign; GnomAD effective popmax AF = 0.478 — exceeds 1% threshold (B1 applied)
	B3Computational evidence does not support deleterious effect		Computational evidence does not support a deleterious effect; Missense variant — primary computational scorer does not support an oncogenic/deleterious effect; supports B3
