Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_Strong
The NM_003640.5(ELP1):c.3417G>C(p.Leu1139Phe) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000198 in 1,614,036 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. L1139L) has been classified as Likely benign.

not provided Uncertain:3
This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 1139 of the ELP1 protein (p.Leu1139Phe). This variant is present in population databases (rs202080366, gnomAD 0.05%). 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: 455965). 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. -
- -
In silico analysis indicates that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
not specified Uncertain:1
The c.3417G>C (p.L1139F) alteration is located in exon 32 (coding exon 31) of the IKBKAP gene. This alteration results from a G to C substitution at nucleotide position 3417, causing the leucine (L) at amino acid position 1139 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
