<p>The complement system is a major mediator of innate immunity. The first enzymatic event in the cascade of the classical pathway of complement is the activation of its first component, C1. C1 is a multimolecular complex consisting of 2 loosely interacting entities: C1q (see <a href="/entry/120550">120550</a>), the recognition subunit, and C1r(2)/C1s(2), the catalytic one. C1r(2)/C1s(2) is a tetrameric Ca(2+)-dependent complex of C1r and C1s (<a href="/entry/120580">120580</a>), 2 serine-proteinase zymogens.

<span class="mim-text-font">
<p>The complement system is a major mediator of innate immunity. The first enzymatic event in the cascade of the classical pathway of complement is the activation of its first component, C1. C1 is a multimolecular complex consisting of 2 loosely interacting entities: C1q (see 120550), the recognition subunit, and C1r(2)/C1s(2), the catalytic one. C1r(2)/C1s(2) is a tetrameric Ca(2+)-dependent complex of C1r and C1s (120580), 2 serine-proteinase zymogens. C1r acts by transforming the activation signal (the fixation of C1q on activating reagents, e.g., immune complexes) into an enzymic activity (summary by Journet and Tosi, 1986). </p>

<p>By means of a cDNA in somatic cell hybrids, Cohen-Haguenauer et al. (1986) assigned the C1R and C1S genes to chromosome 12. Leppert et al. (1987) found a maximum lod score of 5.99 at theta = 0.038 for linkage between C1S and one of the PRP loci (see 168710); the maximum lod score between C1R and another PRP locus was 4.21 at theta = 0.001. Although C1r and C1s are structurally and functionally similar, with a significant degree of sequence homology suggesting origin by gene duplication, cDNA probes for human C1r and C1s do not cross-hybridize even at mild stringency conditions and are therefore gene-specific. Using a panel of human-rodent cell hybrids, Nguyen et al. (1988) independently assigned the C1r and C1s genes to chromosome 12. In situ hybridization confirmed these assignments and localized the genes to 12p13. </p><p>In a study of 5 families heterozygous at both the C1R and the C1S locus, Lyons et al. (1989) found evidence consistent with, but not proving, linkage of the loci; maximum lod score = 1.505 at theta = 0.00. </p><p>By hybridization of C1r and C1s probes to restriction endonuclease fragments of genomic DNA, Tosi et al. (1987) demonstrated close physical linkage of the genes. This finding was consistent with their evolution through tandem gene duplication and was also consistent with the previously observed combined hereditary deficiencies of C1r and C1s (see 216950). Their coordinate expression may depend on the close linkage. The 2 genes lie in a DNA stretch not longer than 50 kb. </p><p>By DNA blotting and sequencing analyses of genomic DNA and of an isolated genomic DNA clone, Kusumoto et al. (1988) showed that the C1r and C1s genes are closely located in a 'tail-to-tail' arrangement at a distance of about 9.5 kb. </p>

<p>Kamboh and Ferrell (1986) demonstrated genetic polymorphism of C1R using the high-resolving power of isoelectric focusing in 6M urea followed by immunoblotting. Kamboh et al.

In affected members of 15 unrelated families with the periodontal type of Ehlers-Danlos syndrome (EDSPD1; 130080), Kapferer-Seebacher et al. (2016) identified heterozygosity for missense or in-frame insertion/deletion mutations in the C1R gene (see, e.g., 613785.0001-613785.0007). The mutations segregated with disease in the families and none of the mutations were found in the ExAC, 1000 Genomes Project, ClinVar, or dbSNP (March 2016) databases. The authors stated that the mutations appeared to have gain-of-function effects. </p>

<p>In a large 5-generation Austrian family (family 1) with the periodontal type of Ehlers-Danlos syndrome (EDSPD1; 130080), Kapferer-Seebacher et al. (2016) identified heterozygosity for a c.149_150TC-AT change (c.149_150TC-AT, NM_001733.4) in the C1R gene, resulting in a val50-to-asp substitution (val32-to-asp (V32D) in the mature protein) at an evolutionarily conserved residue within the CUB1 collagen-binding domain. The mutation segregated fully with disease in the family, and was not found in the ExAC, 1000 Genomes Project, ClinVar, or dbSNP (March 2016) databases. Western blots of HEK293 cells and supernatants in which V50D had been overexpressed indicated that the abnormal C1R protein was retained in the cell but could undergo autoactivation that might lead to interaction with off-target substrates. In addition, mutation-transfected cells showed an increased proportion of dilated cisternae of the rough endoplasmic reticulum compared to controls. Kapferer-Seebacher et al. (2016) noted that unlike previously reported families with EDSPD, none of the affected individuals in this family exhibited pretibial discoloration. </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
