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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: CUL7 c.4951A>C (p.Thr1651Pro) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 4.9e-05 in 247254 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in CUL7 causing Three M Syndrome 1 (4.9e-05 vs 0.0011), allowing no conclusion about variant significance. To our knowledge, no occurrence of c.4951A>C in individuals affected with Three M Syndrome 1 and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 2136666). Based on the evidence outlined above, the variant was classified as uncertain significance. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.4951A>C (p.T1651P) alteration is located in exon 26 (coding exon 25) of the CUL7 gene. This alteration results from a A to C substitution at nucleotide position 4951, causing the threonine (T) at amino acid position 1651 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces threonine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 1651 of the CUL7 protein (p.Thr1651Pro). This variant is present in population databases (rs780899726, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with CUL7-related conditions. ClinVar contains an entry for this variant (Variation ID: 2136666). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt CUL7 protein function with a negative predictive value of 80%. 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. -
