This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 345 of the DBH protein (p.Asp345Asn). This variant is present in population databases (rs267606761, gnomAD 0.01%). 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. Experimental studies have shown that this missense change affects DBH function (PMID: 21209083). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). ClinVar contains an entry for this variant (Variation ID: 217764). This variant is also known as p.Asp331Asn. This missense change has been observed in individual(s) with dopamine beta-hydroxylase deficiency (PMID: 11857564). -
