Genes affected

IKBKG (HGNC:5961): (inhibitor of nuclear factor kappa B kinase regulatory subunit gamma) This gene encodes the regulatory subunit of the inhibitor of kappaB kinase (IKK) complex, which activates NF-kappaB resulting in activation of genes involved in inflammation, immunity, cell survival, and other pathways. Mutations in this gene result in incontinentia pigmenti, hypohidrotic ectodermal dysplasia, and several other types of immunodeficiencies. A pseudogene highly similar to this locus is located in an adjacent region of the X chromosome. [provided by RefSeq, Mar 2016]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM1: In a helix (size 44) in uniprot entity NEMO_HUMAN there are 8 pathogenic changes around while only 0 benign (100%) in ENST00000594239.6
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.812
• PP5: Variant X-154563602-G-A is Pathogenic according to our data. Variant chrX-154563602-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 11468.Status of the report is no_assertion_criteria_provided, 0 stars.
