Genes affected

CAND1 (HGNC:30688): (cullin associated and neddylation dissociated 1) This gene encodes an essential regulator of Cullin-RING ubiquitin ligases, which are in involved in ubiquitinylation of proteins degraded by the Ub proteasome system. The encoded protein binds to unneddylated cullin-RING box protein complexes and acts as an inhibitor of cullin neddylation and of Skp1, cullin, and F box ubiquitin ligase complex assembly and activity. In mammalian cell culture, this protein predominantly localizes to the cytoplasm. Knockdown of this gene in preadipocytes results in blocked adipogenesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2016]

The c.2068A>G (p.I690V) alteration is located in exon 10 (coding exon 10) of the CAND1 gene. This alteration results from a A to G substitution at nucleotide position 2068, causing the isoleucine (I) at amino acid position 690 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
