Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The ENST00000374647.10(ELP1):c.3854C>T(p.Pro1285Leu) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000508 in 1,614,008 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/23 in silico tools predict a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. P1285P) has been classified as Uncertain significance.

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]

The c.3854C>T (p.P1285L) alteration is located in exon 35 (coding exon 34) of the IKBKAP gene. This alteration results from a C to T substitution at nucleotide position 3854, causing the proline (P) at amino acid position 1285 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1285 of the ELP1 protein (p.Pro1285Leu). This variant is present in population databases (rs199813856, gnomAD 0.03%). 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: 566098). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
