Genes affected

HES7 (HGNC:15977): (hes family bHLH transcription factor 7) This gene encodes a member of the hairy and enhancer of split family of bHLH transcription factors. The mouse ortholog of this gene is regulated by Notch signaling. The protein functions as a transcriptional repressor, and is implicated in correct patterning of the axial skeleton. A mutation in this gene has been shown to result in spondylocostal dysostosis. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Sep 2009]

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 output the following: SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 1362098). This variant has not been reported in the literature in individuals affected with HES7-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 184 of the HES7 protein (p.Ala184Val). -
