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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.34245545).

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000282 (43/152234) while in subpopulation AFR AF = 0.000963 (40/41542). AF 95% confidence interval is 0.000726. There are 0 homozygotes in GnomAd4. There are 14 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces phenylalanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1694 of the CUL7 protein (p.Phe1694Val). This variant is present in population databases (rs150979209, gnomAD 0.08%). 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: 286956). 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.5080T>G (p.F1694V) alteration is located in exon 26 (coding exon 25) of the CUL7 gene. This alteration results from a T to G substitution at nucleotide position 5080, causing the phenylalanine (F) at amino acid position 1694 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
