Variant summary

Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PS1_Moderate PM1 PM5 PP3_Moderate

The NM_001099857.5(IKBKG):c.1250G>A(p.Cys417Tyr) variant causes a missense change. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as not provided (no stars). Another nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin UniProt. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C417F) has been classified as Pathogenic.

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 Likely_pathogenic. Variant got 8 ACMG points.

• PS1: Transcript NM_001099857.5 (IKBKG) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in UniProt
• PM1: In a zinc_finger_region CCHC NOA-type (size 30) in uniprot entity NEMO_HUMAN there are 6 pathogenic changes around while only 0 benign (100%) in NM_001099857.5
• PM5: Other missense variant is known to change same aminoacid residue: Variant chrX-154564451-G-T is described in ClinVar as [Pathogenic]. Clinvar id is 11456.Status of the report is no_assertion_criteria_provided, 0 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.882
