Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the SGO1 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: Plays a central role in chromosome cohesion during mitosis by preventing premature dissociation of cohesin complex from centromeres after prophase, when most of cohesin complex dissociates from chromosomes arms. May act by preventing phosphorylation of the STAG2 subunit of cohesin complex at the centromere, ensuring cohesin persistence at centromere until cohesin cleavage by ESPL1/separase at anaphase. Essential for proper chromosome segregation during mitosis and this function requires interaction with PPP2R1A. Its phosphorylated form is necessary for chromosome congression and for the proper attachment of spindle microtubule to the kinetochore. Necessary for kinetochore localization of PLK1 and CENPF. May play a role in the tension sensing mechanism of the spindle-assembly checkpoint by regulating PLK1 kinetochore affinity. Isoform 3 plays a role in maintaining centriole cohesion involved in controlling spindle pole integrity. Involved in centromeric enrichment of AUKRB in prometaphase. {ECO:0000269|PubMed:15604152, ECO:0000269|PubMed:15723797, ECO:0000269|PubMed:15737064, ECO:0000269|PubMed:16580887, ECO:0000269|PubMed:17617734, ECO:0000269|PubMed:17621308, ECO:0000269|PubMed:18331714, ECO:0000269|PubMed:20739936}.
• Disease: DISEASE: Chronic atrial and intestinal dysrhythmia (CAID) [MIM:616201]: A disease characterized by dysregulation of the cardiac sinus node resulting in sick sinus syndrome, in association with chronic intestinal pseudo-obstruction, a disorder of gastrointestinal motility in which intestinal obstruction occurs in the absence of a mechanical obstacle. {ECO:0000269|PubMed:25282101}. Note=The disease is caused by mutations affecting the gene represented in this entry.
