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 Uncertain_significance. Variant got 2 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

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=0.27273566).

Collection Method: clinical testing

The c.38G>A (p.G13D) alteration is located in exon 1 (coding exon 1) of the USP7 gene. This alteration results from a G to A substitution at nucleotide position 38, causing the glycine (G) at amino acid position 13 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
