Genes affected
USP7 (HGNC:12630): (ubiquitin specific peptidase 7) The protein encoded by this gene belongs to the peptidase C19 family, which includes ubiquitinyl hydrolases. This protein deubiquitinates target proteins such as p53 (a tumor suppressor protein) and WASH (essential for endosomal protein recycling), and regulates their activities by counteracting the opposing ubiquitin ligase activity of proteins such as HDM2 and TRIM27, involved in the respective process. Mutations in this gene have been implicated in a neurodevelopmental disorder. [provided by RefSeq, Mar 2016]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

PP2
Missense variant in the USP7 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 14 curated pathogenic missense variants (we use a threshold of 10). The gene has 11 curated benign missense variants. Gene score misZ: 5.648 (above the threshold of 3.09). Trascript score misZ: 6.8588 (above the threshold of 3.09). GenCC associations: The gene is linked to Hao-Fountain syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.108566135).
BS2
High AC in GnomAdExome4 at 5 AD gene.

This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 23 of the USP7 protein (p.Met23Val). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with USP7-related conditions. ClinVar contains an entry for this variant (Variation ID: 2570929). 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 tolerated. 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. -
