Variant summary
Our verdict is Uncertain significance. The variant received 5 ACMG points: 5P and 0B. PM1PM2PP2
The NM_001972.4(ELANE):c.214G>A(p.Val72Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000256 in 1,562,686 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V72L) has been classified as Uncertain significance.

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. This variant disrupts the p.Val72 amino acid residue in ELANE. Other variant(s) that disrupt this residue have been observed in individuals with ELANE-related conditions (PMID: 22510773, 23463630), which suggests that this may be a clinically significant amino acid residue. This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 72 of the ELANE protein (p.Val72Met). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ELANE-related conditions. ClinVar contains an entry for this variant (Variation ID: 16744). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on ELANE protein function. Experimental studies have shown that this missense change affects ELANE function (PMID: 11278653). -
