It was not observed in the large and broad cohorts of the Genome Aggregation Database (http://gnomad.broadinstitute.org), but has been reported in ClinVar (Variation ID 456684). In silico tools suggest the impact of the variant on protein function is benign, though these predictions have not been confirmed by functional studies. The evidence is insufficient to meet ACMG/AMP criteria for classifying the variant as benign or pathogenic. Thus, the clinical significance of this variant is currently uncertain. (less)

This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CEBPA-related conditions. ClinVar contains an entry for this variant (Variation ID: 456684). 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) performed at Invitae indicates that this missense variant is not expected to disrupt CEBPA protein function with a negative predictive value of 80%. 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. (less)

Comment:

This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 14 of the CEBPA protein (p.Pro14Ala). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CEBPA-related conditions. ClinVar contains an entry for this variant (Variation ID: 456684). 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) performed at Invitae indicates that this missense variant is not expected to disrupt CEBPA protein function with a negative predictive value of 80%. 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.

Comment:

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
