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]
IKBKE-AS1 (HGNC:32061): (IKBKE antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 03, 2023The c.1988C>T (p.A663V) alteration is located in exon 20 (coding exon 18) of the IKBKE gene. This alteration results from a C to T substitution at nucleotide position 1988, causing the alanine (A) at amino acid position 663 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
