Genes affected

CARD6 (HGNC:16394): (caspase recruitment domain family member 6) This gene encodes a protein that contains a caspase recruitment domain (CARD), an antiparallel six-helical bundle that mediates homotypic protein-protein interactions. The encoded protein is a microtubule-associated protein that has been shown to interact with receptor-interacting protein kinases and positively modulate signal transduction pathways converging on activation of the inducible transcription factor NF-kB.

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.06809363).

The c.550G>C (p.G184R) alteration is located in exon 2 (coding exon 2) of the CARD6 gene. This alteration results from a G to C substitution at nucleotide position 550, causing the glycine (G) at amino acid position 184 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
