C1Q deficiency 3(C1QD3)

MedGen UID:
1841059
Concept ID:
C5830423
Disease or Syndrome
Synonyms: C1q DEFICIENCY 3; C1Q DEFICIENCY 3; C1QD3
 
Gene (location): C1QC (1p36.12)
 
Monarch Initiative: MONDO:0958188
OMIM®: 620322

Definition

C1q deficiency (C1QD) is a rare autosomal recessive disorder characterized by recurrent skin lesions, chronic infections, and an increased risk of autoimmune diseases, particularly systemic lupus erythematosus (SLE; see 152700) or SLE-like diseases. It has also been associated with chronic glomerulonephritis and renal failure. C1q deficiency presents in 2 different forms, absent C1q protein or presence of a dysfunctional molecule (summary by Topaloglu et al., 1996 and Vassallo et al., 2007). For a discussion of genetic heterogeneity of C1q deficiency, see 613652. [from OMIM]

Clinical features

From HPO
Antinuclear antibody positivity
MedGen UID:
101792
Concept ID:
C0151480
Laboratory or Test Result
The presence of autoantibodies in the serum that react against nuclei or nuclear components.
Recurrent bacterial meningitis
MedGen UID:
375697
Concept ID:
C1845604
Disease or Syndrome
An increased susceptibility to bacterial meningitis as manifested by a medical history of recurrent episodes of bacterial meningitis.
Discoid lupus erythematosus
MedGen UID:
1811126
Concept ID:
C5574816
Disease or Syndrome
Cutaneous lesion that develops as a dry, scaly, red patch that evolves to an indurated and hyperpigmented plaque with adherent scale. Scarring may result in central white patches (loss of pigmentation) and skin atrophy.
Decreased circulating C1q concentration
MedGen UID:
1841603
Concept ID:
C5826513
Finding
Concentration or activity of the C1q protein in the blood circulation below the lower limit of normal. C1q is the first component of the classical pathway and is composed of the C1qA chain, C1qB chain, and C1qC chain, which are encoded by C1qA, C1qB, and C1qC genes.
Neonatal omphalitis
MedGen UID:
510678
Concept ID:
C0158947
Disease or Syndrome
An infection of the umbilicus and/or surrounding tissues occurring in the neonatal period.
