Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the USP27X gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Deubiquitinase that can reduce the levels of BCL2L11/BIM ubiquitination and stabilize BCL2L11 in response to the RAF-MAPK- degradation signal. By acting on BCL2L11 levels, may counteract the anti-apoptotic effects of MAPK activity. {ECO:0000250|UniProtKB:Q8CEG8}.
• Disease: DISEASE: Mental retardation, X-linked 105 (MRX105) [MIM:300984]: A form of mental retardation, a disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. Intellectual deficiency is the only primary symptom of non-syndromic X-linked mental retardation, while syndromic mental retardation presents with associated physical, neurological and/or psychiatric manifestations. {ECO:0000269|PubMed:25644381}. Note=The disease is caused by mutations affecting the gene represented in this entry.
