Test Code NEMO Known IKBKG (NEMO) Known Mutation

Important Note

Test availability is limited to Seattle Children’s Hospital and University of Washington patients.

Clinical System Name

IKBKG (NEMO) Known Mutation

Synonyms

IKBKG, AMCBX1, FIP-3, FIP3, Fip3, IKK-gamma, IP, IP1, IP2, IPD2, ZC2HC9

Description

This test involves targeted analysis for mutations previously identified through clinical testing of a family member or  research testing of the individual.  It can be used for carrier testing at-risk relatives and prenatal testing for confirmed carriers. Mutations must be known. For full gene sequencing please see IKBKG Gene Sequencing.

 

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
