Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the OTUD6B 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: Isoform 1: Deubiquitinating enzyme that may play a role in the ubiquitin-dependent regulation of protein synthesis, downstream of mTORC1 (PubMed:21267069, PubMed:27864334). May associate with the protein synthesis initiation complex and modify its ubiquitination to repress translation (PubMed:27864334). May also repress DNA synthesis and modify different cellular targets thereby regulating cell growth and proliferation (PubMed:27864334). May also play a role in proteasome assembly and function (PubMed:28343629). {ECO:0000269|PubMed:21267069, ECO:0000269|PubMed:27864334, ECO:0000269|PubMed:28343629}.
• Disease: DISEASE: Intellectual developmental disorder with dysmorphic facies, seizures, and distal limb anomalies (IDDFSDA) [MIM:617452]: An autosomal recessive severe multisystem disorder characterized by poor overall growth, developmental delay, early- onset seizures, intellectual disability, and dysmorphic features. Additional features include microcephaly, absent speech, hypotonia, feeding difficulties, structural brain abnormalities, congenital malformations including congenital heart disease, and musculoskeletal features. {ECO:0000269|PubMed:28343629}. Note=The disease is caused by mutations affecting the gene represented in this entry.
