Genes affected

IKBKE (HGNC:14552): (inhibitor of nuclear factor kappa B kinase subunit epsilon) IKBKE is a noncanonical I-kappa-B (see MIM 164008) kinase (IKK) that is essential for regulating antiviral signaling pathways. IKBKE has also been identified as a breast cancer (MIM 114480) oncogene and is amplified and overexpressed in over 30% of breast carcinomas and breast cancer cell lines (Hutti et al., 2009 [PubMed 19481526]).[supplied by OMIM, Oct 2009]

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=0.2044906).

The c.1047C>A (p.H349Q) alteration is located in exon 10 (coding exon 8) of the IKBKE gene. This alteration results from a C to A substitution at nucleotide position 1047, causing the histidine (H) at amino acid position 349 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
