Description

This sequence change replaces threonine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 394 of the SERPING1 protein (p.Thr394Pro). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with hereditary angioedema (PMID: 8755917). This variant is also known as T372P. 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 expected to disrupt SERPING1 protein function with a positive 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.
