Genes affected

ELP1 (HGNC:5959): (elongator acetyltransferase complex subunit 1) The protein encoded by this gene is a scaffold protein and a regulator for three different kinases involved in proinflammatory signaling. The encoded protein can bind NF-kappa-B-inducing kinase and I-kappa-B kinases through separate domains and assemble them into an active kinase complex. Mutations in this gene have been associated with familial dysautonomia. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jan 2016]

Uncertain significance, criteria provided, single submitter	clinical testing	CeGaT Center for Human Genetics Tuebingen	Aug 01, 2018	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Aug 16, 2022	This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 1011 of the IKBKAP protein (p.Arg1011His). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with IKBKAP-related conditions. ClinVar contains an entry for this variant (Variation ID: 526186). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

The c.3032G>A (p.R1011H) alteration is located in exon 28 (coding exon 27) of the IKBKAP gene. This alteration results from a G to A substitution at nucleotide position 3032, causing the arginine (R) at amino acid position 1011 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
