The mutation was identified by whole-exome sequencing and confirmed by Sanger sequencing. Neither parent had the mutation.

<span class="mim-text-font">
<p>Ornithine decarboxylase (EC 4.1.1.17) catalyzes the conversion of ornithine to putrescine in the first and apparently rate-limiting step in polyamine biosynthesis. The activity of the enzyme fluctuates rapidly in response to various growth-promoting stimuli, and ODC exhibits one of the most rapid turnover rates of mammalian proteins. Winqvist et al. (1986) used a mouse cDNA probe to isolate human cDNA clones from a library prepared from human liver mRNA. Unlike the mouse genome, there are only a few ODC genes in the human genome. </p><p>Hickok et al. (1987) deduced the complete amino acid sequence of human ODC from a complementary cDNA. </p>

<strong>Gene Function</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Ornithine decarboxylase, the first enzyme in polyamine synthesis, is a transcriptional target of MYC (190080) and a modifier of APC (611731)-dependent tumorigenesis. ODC promoter activity is influenced by cooperative interactions involving neighboring E-boxes (Walhout et al., 1997). A polymorphic site, situated between 2 E-boxes, was identified in the human ODC promoter and shown to affect MYC-dependent ODC promoter activity in rodent fibroblasts (Guo et al., 2000). A GC box in the proximal promoter of the ODC1 gene is required for basal and induced transcriptional activity. Law et al. (1998) determined that SP1 (189906) and ZBP89 (601897) bound to this region in a mutually exclusive manner, and that ZBP89 inhibited SP1-activated ODC1 promoter activity following transfection in insect cells. </p><p>Translation of ODC, the rate-limiting enzyme in the biosynthesis of polyamines, peaks twice during the cell cycle, at the G1/S transition and at G2/M. Pyronnet et al. (2000) identified a cap-independent internal ribosome entry site (IRES) in the ODC mRNA that functions exclusively at G2/M. This ensures elevated levels of polyamines, which are implicated in mitotic spindle formation and chromatin condensation. MYC mRNA also contains an IRES that functions during mitosis. Thus, Pyronnet et al. (2000) concluded that IRES-dependent translation is likely to be a general mechanism to synthesize short-lived proteins even at mitosis, when cap-dependent translation is interdicted. </p>

<strong>Mapping</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Winqvist et al. (1986) observed that human DNA fragments segregated with 2pter-p23 and 7cen-qter in mouse-human somatic cell hybrids containing rearranged chromosomes. Despite the fact that that segment of chromosome 2 contains the NMYC gene (164840), which is involved in a number of neoplasms, coamplification of ODC was not found. The ODC gene on chromosome 2 was tentatively called ODC1 and that on 7 ODC2 (ODCP). </p><p>Yang-Feng et al. (1987) assigned ODC to 2p25-p24 by Southern blot analysis of DNA from somatic cell hybrids and by in situ hybridization. They also assigned the corresponding gene in the mouse to chromosome 12. ODC is presumably closely linked to RRM2 (180390) because both are amplified in human and mouse hydroxyurea-resistant cells. By in situ hybridization, Radford et al. (1987) narrowed the localization to 2p25. The chromosome 2 locus appears to be the functional ODC gene. </p><p>Cox et al. (1988) used a genomic probe specific for a functional mouse Odc gene in conjunction with a panel of Chinese hamster x mouse somatic cell hybrids to assign Odc to mouse chromosome 12. There is considerable genetic homology between a region of mouse chromosome 12 and the distal short arm of human chromosome 2. Villani et al. (1989) also presented data on the mapping of Odc on mouse chromosome 12. </p><p><strong><em>Pseudogenes</em></strong></p><p>
Using a chromosomal rearrangement and somatic cell hybrids, Radford et al. (1987) assigned the ODC2 locus to 7q31-qter. This pseudogene is also symbolized ODCP.</p>

<p>In 4 unrelated patients with Bachmann-Bupp syndrome (BABS; 619075), Rodan et al. (2018) identified de novo heterozygous mutations in the ODC1 gene (165640.0002-165640.0005). All of the mutations were identified by trio whole-exome sequencing. The resultant proteins were predicted to escape nonsense-mediated decay and to have a truncated C terminus, leading to decreased protein degradation and a net increase in enzyme activity. Rodan et al. (2018) noted that the close proximity of the mutations suggested a mutation hotspot. A gain in ODC activity was supported by increased N-acetylputrescine levels in plasma from one of the patients. </p><p>Bupp et al. (2018) identified a de novo heterozygous nonsense mutation in the ODC1 gene (K448X; 165640.0006) in a 32-month-old girl with BABS. The mutation was identified by whole-exome sequencing and confirmed by Sanger sequencing. Molecular modeling suggested that due to lack of a C terminus in the mutant protein, antizyme binding does not induce ODC degradation, leading to accumulation of active protein. </p><p><strong><em>Associations Pending Confirmation</em></strong></p><p>
Martinez et al. (2003) assessed the relationship between an ODC polymorphism (165640.0001) and the risk of abnormal recurrence in participants in a colon cancer prevention trial. They further investigated whether this association was modified by aspirin use. Epidemiologic analyses revealed a substantial and statistically significant affect of the ODC polymorphism on risk of adenoma recurrence and aspirin uses. They presented experimental studies in cell culture models that may explain the epidemiologic results, suggesting that one likely mechanism for both ODC polymorphism and aspirin is their effect on intracellular polyamine pools. </p>

Martinez et al. (2003) found that individuals homozygous for the minor ODC1 A allele who reported using aspirin were 0.10 times as likely to have an adenoma recurrence as non-aspirin users homozygous for the major G allele. MAD1 selectively suppressed the activity of the ODC1 promoter containing the A allele, but not the G allele, in a human colon cancer-derived cell line. Aspirin did not affect ODC1 allele-specific promoter activity but did activate polyamine catabolism and lower polyamine content in the same colon cancer-derived cell line. Martinez et al. (2003) suggested that the ODC1 polymorphism and aspirin act independently to reduce the risk of adenoma recurrence by suppressing synthesis and activating catabolism, respectively, of colonic mucosal polyamines. These findings confirm the hypothesis that the ODC1 polymorphism is a genetic marker for colon cancer risk, and support the use of ODC1 inhibitors and aspirin, or other nonsteroidal antiinflammatory drugs (NSAIDs), in combination as a strategy for colon cancer prevention. </p><p>Hamosh (2020) noted that this variant is present in 10,196 of 31,084 alleles and in 1,685 homozygotes in the gnomAD database (10/13/2020).</p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
