Genes affected

NAXE (HGNC:18453): (NAD(P)HX epimerase) The product of this gene interacts with apolipoprotein A-I (apoA-I), the major apolipoprotein of high-density lipoproteins (HDLs). It is secreted into some bodily fluids, and its synthesis and secretion are stimulated in vitro by incubating cells with apoA-I. The human genome contains related pseudogenes.

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. 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 tolerated. This variant has not been reported in the literature in individuals affected with NAXE-related conditions. This variant is present in population databases (rs773049023, gnomAD 0.01%). This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 56 of the NAXE protein (p.Val56Leu). -
