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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1925C>T (p.T642M) alteration is located in exon 18 (coding exon 17) of the IKBKAP gene. This alteration results from a C to T substitution at nucleotide position 1925, causing the threonine (T) at amino acid position 642 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 642 of the ELP1 protein (p.Thr642Met). This variant is present in population databases (rs377020122, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with ELP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 526187). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The methionine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
