Genes affected
CIC (HGNC:14214): (capicua transcriptional repressor) The protein encoded by this gene is an ortholog of the Drosophila melanogaster capicua gene, and is a member of the high mobility group (HMG)-box superfamily of transcriptional repressors. This protein contains a conserved HMG domain that is involved in DNA binding and nuclear localization, and a conserved C-terminus. Studies suggest that the N-terminal region of this protein interacts with Atxn1 (GeneID:6310), to form a transcription repressor complex, and in vitro studies suggest that polyglutamine-expansion of ATXN1 may alter the repressor activity of this complex. Mutations in this gene have been associated with olidogdendrogliomas (PMID:21817013). In addition, translocation events resulting in gene fusions of this gene with both DUX4 (GeneID:100288687) and FOXO4 (GeneID:4303) have been associated with round cell sarcomas. There are multiple pseudogenes of this gene found on chromosomes 1, 4, 6, 7, 16, 20, and the Y chromosome. Alternative splicing results in multiple transcript variants encoding different isoforms.

The missense c.281A>G (p.Lys94Arg) variant in CIC gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The p.Lys94Arg variant is present with allele frequency of 0% in gnomAD Exomes. This variant has been submitted to the ClinVar database as Uncertain Significance. Computational evidence (SIFT - Damaging and MutationTaster - Polymorphism) predicts conflicting evidence on protein structure and function for this variant. The reference amino acid at this position on CIC gene is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Lys at position 94 is changed to a Arg changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as Variant of Uncertain Significance (VUS). -
