Genes affected

AHDC1 (HGNC:25230): (AT-hook DNA binding motif containing 1) This gene encodes a protein containing two AT-hooks, which likely function in DNA binding. Mutations in this gene were found in individuals with Xia-Gibbs syndrome. [provided by RefSeq, Jun 2014]

This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1590 of the AHDC1 protein (p.Ala1590Val). This variant is present in population databases (rs778493358, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with AHDC1-related conditions. 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. -
