Description

This missense change has been observed in individual(s) with clinical features of dyslipidemia (PMID: 32041611). This variant is present in population databases (rs761948955, gnomAD 0.03%). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 193 of the APOA5 protein (p.Pro193Leu). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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.
