CDK13 mutations in melanoma (see <a href="/entry/155600">155600</a>), especially those in the kinase domain, abrogated its kinase activity and produced dominant-negative activity over wildtype CDK13. CDK13 mutations associated with melanoma caused accumulation of prematurely terminated RNAs (ptRNAs) generated from existing cleavage and polyadenylation sites found in intronic DNA. ptRNAs accumulated posttranscriptionally due to loss of degradation by the nuclear exosome in CDK13 mutant cells. Rather than being degraded, ptRNAs were exported to the cytoplasm, where they, including their intronic sequences, were translated into truncated proteins. Mutant CDK13 expression caused inefficient recruitment of the PAXT complex, which degrades ptRNAs, leading to disruption of the polyA RNA exosome and stabilization of ptRNAs. Database analysis and studies with a zebrafish model confirmed that ptRNA accumulation is oncogenic. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=37079685" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p>

The authors also reviewed 20 previously reported patients with CDK13 pathogenic variants. Of the total of 29 patients with CDK13 pathogenic variants, mutations in 27 were de novo and in 2 were of unknown inheritance due to parental samples being unavailable. All variants were missense mutations predicted to impact the protein kinase domain, with clustering in the ATP-binding and magnesium binding sites. More than half (15/29) affected asparagine-842, (14 patients with N842S, <a href="#0001">603309.0001</a> and 1 patient with N842D, <a href="#0005">603309.0005</a>), suggesting its importance in magnesium binding. The authors noted that the clustering of missense mutations within a single protein domain and the lack of loss-of-function variants is consistent with a possible gain-of-function mechanism. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=28807008" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p><p><a href="#4" class="mim-tip-reference" title="Hamilton, M.

Functional studies of the variant and studies of patient cells were not performed, but molecular modeling predicted that the variant would result in altered catalytic function with a dominant-negative effect. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=29021403" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p>

<p>Lapidot-Lifson et al. (1992) cloned a glioblastoma cDNA encoding a protein related to the S. pombe cdc2 kinase. They designated the predicted 418-amino acid protein CHED, for cholinesterase-related cell division controller. The CHED protein shares 34 to 42% sequence identity with human CDC2 (116940), S. cerevisiae Cdc28, and S. pombe Cdc2, 3 functionally interchangeable proteins. Northern blot analysis revealed that CHED is expressed as 2.2- to 2.3-kb mRNAs in several fetal tissues and tumor cell lines. </p><p>Marques et al. (2000) cloned full-length CDC2L5 from sea urchin and human. The full-length human protein contains 1,512 amino acids. Both human and sea urchin CDC2L5 contain a conserved kinase domain surrounded by N and C termini of more than 400 amino acids, and they belong to a subfamily of high molecular mass CDC2-related kinases with PITAI/VRE motifs. Northern blot analysis detected Cdc2l5 during sea urchin early embryogenesis. In human, CDC2L5 showed ubiquitous expression, with higher levels in liver and placenta. The authors identified a putative CDC2L5 splice variant encoding an isoform of 1,452 amino acids that showed a similar expression pattern as full-length CDC2L5. Immunofluorescence assays detected CDC2L5 protein in nuclei of transfected HEK 293 cells. </p><p>By Western blot analysis, Novakova et al. (2019) showed that Cdk13 was expressed in multiple embryonic mouse organs, with highest expression in brain, followed by lung, kidney, and heart. In adult mice, Cdk13 was strongly expressed in retina, testis, ovary, uterus, and gall bladder, with lower expression in urinary bladder. </p>

<strong>Gene Function</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Using an antisense oligonucleotide, Lapidot-Lifson et al. (1992) found that reduced CHED expression selectively inhibited megakaryocyte development in murine bone marrow cultures but did not prevent other hematopoietic pathways. Antisense mRNA inhibition of BCHE (177400) expression had a similar effect. The authors suggested that CHED and BCHE are interrelated components responsive to cholinergic signals in the hematopoietic pathway. They stated that a link between cholinergic signaling and cell division might be mediated through individual CDC proteins in a cell lineage-specific manner. </p><p>Using mass spectrometric techniques and reciprocal immunoprecipitation analysis with HEK293 cells, Blazek et al. (2011) found that CYCK interacted with CDK12 (615514) and CDK13 in separate protein complexes. Microarray and RT-PCR analyses showed that knockdown of CYCK or CDK12, but not CDK13, altered expression of long complex genes and induced DNA damage and cell-cycle checkpoint. Blazek et al. (2011) concluded that the CYCK-CDK12 and CYCK-CDK13 complexes have unique functions in gene regulation. </p><p>Using database analysis and experimental approaches, Insco et al. (2023) showed that CDK13 had properties consistent with a tumor suppressor. CDK13 mutations in melanoma (see 155600), especially those in the kinase domain, abrogated its kinase activity and produced dominant-negative activity over wildtype CDK13. CDK13 mutations associated with melanoma caused accumulation of prematurely terminated RNAs (ptRNAs) generated from existing cleavage and polyadenylation sites found in intronic DNA. ptRNAs accumulated posttranscriptionally due to loss of degradation by the nuclear exosome in CDK13 mutant cells. Rather than being degraded, ptRNAs were exported to the cytoplasm, where they, including their intronic sequences, were translated into truncated proteins. Mutant CDK13 expression caused inefficient recruitment of the PAXT complex, which degrades ptRNAs, leading to disruption of the polyA RNA exosome and stabilization of ptRNAs. Database analysis and studies with a zebrafish model confirmed that ptRNA accumulation is oncogenic. </p>

<p>In 7 unrelated children with congenital heart defects, dysmorphic facial features, and intellectual developmental disorder (CHDFIDD; 617360), Sifrim et al. (2016) identified heterozygous missense mutations in the CDK13 gene (603309.0001-603309.0004). Six of the mutations were proven to have occurred de novo; paternal DNA from the seventh patient was not available, but his mother did not carry the variant. Four patients carried the same mutation (N842S; 603309.0001). All mutations occurred in the highly conserved protein kinase domain, and molecular modeling predicted that the mutations would impair ATP binding, binding of the magnesium ion essential for enzyme activity, or interactions with cyclin K (603544). Six of the patients were ascertained from a cohort of 518 trios in which a child with syndromic congenital heart defects underwent exome sequencing; the seventh patient was 1 of 86 singleton cases. Statistical analysis indicated that de novo missense mutations in the CDK13 gene were significantly enriched in patients compared to those expected under a null mutational model (p = 2.26 x 10(-12), Bonferroni-corrected p = 0.05). Functional studies of the variants and studies of patient cells were not performed. </p><p>In 9 patients with CHDFIDD, Bostwick et al. (2017) identified heterozygous pathogenic variants in the CDK13 gene. Two patients had novel CDK13 missense mutations (e.g., N842D; 603309.0005), while the other 7 had the previously identified recurrent variant N842S (603309.0001). The authors also reviewed 20 previously reported patients with CDK13 pathogenic variants. Of the total of 29 patients with CDK13 pathogenic variants, mutations in 27 were de novo and in 2 were of unknown inheritance due to parental samples being unavailable. All variants were missense mutations predicted to impact the protein kinase domain, with clustering in the ATP-binding and magnesium binding sites. More than half (15/29) affected asparagine-842, (14 patients with N842S, 603309.0001 and 1 patient with N842D, 603309.0005), suggesting its importance in magnesium binding. The authors noted that the clustering of missense mutations within a single protein domain and the lack of loss-of-function variants is consistent with a possible gain-of-function mechanism. </p><p>Hamilton et al. (2018) reported 9 additional unrelated patients with CHDFIDD associated with de novo heterozygous mutations in the CDK13 gene that were identified by whole-exome sequencing (see, e.g., 603309.0001-603309.0002; 603309.0005-603309.0006). Aside from 1 patient with a splice site mutation, all mutations were missense substitution affecting highly conserved residues. All mutations, including the splice site mutation, occurred within the protein kinase domain, and none were found in the gnomAD database. Molecular modeling and structural analysis indicated that all the missense variants would cause changes to bonding and/or structure that would likely lead to significant loss of catalytic activity. Hamilton et al. (2018) postulated a dominant-negative effect wherein the mutant missense variants would sequester cyclin K into inactive complexes or compete with active complexes for binding to substrates. In vitro functional expression studies of the variants were not performed. </p>

<strong>Animal Model</strong>

<span class="mim-text-font">
<p>Novakova et al. (2019) generated mice with Cdk13 deficiency due to homozygosity for a Cdk13 hypomorphic mutation within intron 2 that resulted in residual expression of a truncated protein. Homozygous mutant mice underwent embryonic lethality starting from embryonic day-14.5 (E14.5), with total lethality before E16.5. Compared with wildtype, mutant embryos displayed growth retardation and developmental delay, with improper development of multiple organs, especially heart. Lethality appeared to be caused by heart failure. Mice homozygous for a Cdk13 mutation causing deletion of exons 3 and 4 and no residual expression had a more severe phenotype and earlier lethality with developmental delay. </p>
