Genes affected
FOXC2 (HGNC:3801): (forkhead box C2) This gene belongs to the forkhead family of transcription factors which is characterized by a distinct DNA-binding forkhead domain. The specific function of this gene has not yet been determined; however, it may play a role in the development of mesenchymal tissues. [provided by RefSeq, Jul 2008]
FOXC2-AS1 (HGNC:50665): (FOXC2 antisense RNA 1)

This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 54 of the FOXC2 protein (p.Arg54Leu). 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 disruptive. This variant has not been reported in the literature in individuals affected with FOXC2-related conditions. This variant is present in population databases (rs746195395, gnomAD 0.002%). -
