Invitae RCV003595716 SCV001390328 uncertain significance FG syndrome 2019-05-03 criteria provided, single submitter clinical testing This sequence change replaces histidine with asparagine at codon 769 of the MED12 protein (p.His769Asn). The histidine residue is highly conserved and there is a small physicochemical difference between histidine and asparagine. This variant is present in population databases (rs755014778, ExAC 0.002%). This variant has not been reported in the literature in individuals with MED12-related conditions. 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, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
