Description

This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 907 of the WDR19 protein (p.Ala907Val). This variant is present in population databases (rs201967816, gnomAD 0.02%). This missense change has been observed in individual(s) with craniosynostosis (PMID: 31837199). ClinVar contains an entry for this variant (Variation ID: 691914). 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: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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.
