Complement component C1r/C1s deficiency

The two complement components C1s and C1r coding genes C1S and C1R are in close tail-to-tail position, so it is not surpeising that gross deletions exist affecting both genes, contiguous gene syndrome. Clinically such defects are characterized by susceptibility to infectious disease. As the disorder is rare and the symptoms quite variable almost vanishing with age, it is not yet determined whether inheritance is dominant or recessive.
