Genes affected

CUL7 (HGNC:21024): (cullin 7) The protein encoded by this gene is a component of an E3 ubiquitin-protein ligase complex. The encoded protein interacts with TP53, CUL9, and FBXW8 proteins. Defects in this gene are a cause of 3M syndrome type 1 (3M1). Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2009]

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1222 of the CUL7 protein (p.Arg1222Gln). This variant is present in population databases (rs141899283, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with CUL7-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. -
