Description

This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 104 of the FOXC1 protein (p.Ile104Thr). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of FOXC1-related conditions (Invitae). It has also been observed to segregate with disease in related individuals. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests 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.
