Genes affected

CUL9 (HGNC:15982): (cullin 9) Predicted to enable several functions, including ATP binding activity; metal ion binding activity; and ubiquitin protein ligase binding activity. Involved in microtubule cytoskeleton organization; protein ubiquitination; and regulation of mitotic nuclear division. Located in cytosol. Part of cullin-RING ubiquitin ligase complex.

The CUL9 c.306A>G variant is not predicted to result in an amino acid change (p.=). This variant is predicted to alter splicing based on available splicing prediction software (SpliceAI, Jaganathan et al. 2019. PubMed ID: 30661751). However, the use of computer prediction software is not equivalent to functional evidence. To our knowledge, this variant has not been reported in the literature or in a large population database, indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
