- 17
- Disorders:
- ID, ASD, EP, ADHD
- Last Updated:
- January 24, 2024
Gene Summary:
- DBD Genes Classification
- CHAMP1 is a High Confidence candidate gene classified as Tier 1. Tier 1 genes have three or more de novo pathogenic loss-of-function variants.
- Gene Function
- Required for proper alignment of chromosomes at metaphase and their accurate segregation during mitosis. Involved in the maintenance of spindle microtubules attachment to the kinetochore during sister chromatid biorientation. May recruit CENPE and CENPF to the kinetochore. {ECO:0000269|PubMed:21063390}.
