Entrez Gene summary for C1QC Gene:

This gene encodes a major constituent of the human complement subcomponent C1q. C1q associates with C1r and C1s in

order to yield the first component of the serum complement system. A deficiency in C1q has been associated with

lupus erythematosus and glomerulonephritis. C1q is composed of 18 polypeptide chains: six A-chains, six B-chains,

and six C-chains. Each chain contains a collagen-like region located near the N-terminus, and a C-terminal

globular region. The A-, B-, and C-chains are arranged in the order A-C-B on chromosome 1. This gene encodes the

C-chain polypeptide of human complement subcomponent C1q. Alternatively spliced transcript variants that encode

the same protein have been found for this gene. (provided by RefSeq, Jul 2008)

GeneCards Summary for C1QC Gene:

C1QC (complement component 1, q subcomponent, C chain) is a protein-coding gene. Diseases associated with C1QC include c1q deficiency, and glomerulonephritis. An important paralog of this gene is C1QTNF6.

UniProtKB/Swiss-Prot: C1QC_HUMAN, P02747

Function: C1q associates with the proenzymes C1r and C1s to yield C1, the first component of the serum complement

system. The collagen-like regions of C1q interact with the Ca(2+)-dependent C1r(2)C1s(2) proenzyme complex, and

efficient activation of C1 takes place on interaction of the globular heads of C1q with the Fc regions of IgG or

IgM antibody present in immune complexes

Complement component C1q deficiency (C1QD) [MIM:613652]: A disorder caused by impaired activation of the

complement classical pathway. It generally leads to severe immune complex disease with features of systemic lupus

erythematosus and glomerulonephritis. Note=The disease is caused by mutations affecting the gene represented in
