Definition

Hyper-IgE syndrome-4A with recurrent infections (HIES4A) is an autosomal dominant immunologic disorder characterized by recurrent, mainly sinopulmonary infections associated with increased serum IgE. The phenotype is variable, even within families. Some patients have onset of symptoms in early childhood and develop complications, including bronchiectasis or hemoptysis, whereas others have later onset of less severe infections. Immunologic workup usually shows normal leukocyte levels, although some patients may demonstrate alterations in lymphocyte subsets, including T cells. Affected individuals also have variable skeletal abnormalities, including high-arched palate, hyperextensible joints, scoliosis, and bone fractures. The IL6ST mutations are loss-of-function, although the truncated mutant proteins are expressed and interfere with the wildtype protein in a dominant-negative manner by disrupting IL6 (147620) and IL11 (147681) signaling (summary by Beziat et al., 2020). For a discussion of genetic heterogeneity of hyper-IgE syndrome, see HIES1 (147060). [from OMIM]

Clinical features

From HPO
Clubfoot
MedGen UID:
3130
Concept ID:
C0009081
Congenital Abnormality
Clubfoot is a congenital limb deformity defined as fixation of the foot in cavus, adductus, varus, and equinus (i.e., inclined inwards, axially rotated outwards, and pointing downwards) with concomitant soft tissue abnormalities (Cardy et al., 2007). Clubfoot may occur in isolation or as part of a syndrome (e.g., diastrophic dysplasia, 222600). Clubfoot has been reported with deficiency of long bones and mirror-image polydactyly (Gurnett et al., 2008; Klopocki et al., 2012).
Scoliosis
MedGen UID:
11348
Concept ID:
C0036439
Disease or Syndrome
The presence of an abnormal lateral curvature of the spine.
Increased susceptibility to fractures
MedGen UID:
234655
Concept ID:
C1390474
Finding
An abnormally increased tendency to fractures of bones caused by an abnormal reduction in bone strength that is generally associated with an increased risk of fracture.
Joint hypermobility
MedGen UID:
336793
Concept ID:
C1844820
Finding
The capability that a joint (or a group of joints) has to move, passively and/or actively, beyond normal limits along physiological axes.
Bronchiectasis
MedGen UID:
14234
Concept ID:
C0006267
Disease or Syndrome
Persistent abnormal dilatation of the bronchi owing to localized and irreversible destruction and widening of the large airways.
Bronchomalacia
MedGen UID:
82679
Concept ID:
C0264353
Disease or Syndrome
Weakness or softness of the cartilage in the walls of the bronchial tubes.
Recurrent upper respiratory tract infections
MedGen UID:
154380
Concept ID:
C0581381
Disease or Syndrome
An increased susceptibility to upper respiratory tract infections as manifested by a history of recurrent upper respiratory tract infections (running ears - otitis, sinusitis, pharyngitis, tonsillitis).
Recurrent pneumonia
MedGen UID:
195802
Concept ID:
C0694550
Disease or Syndrome
An increased susceptibility to pneumonia as manifested by a history of recurrent episodes of pneumonia.
Pulmonary pneumatocele
MedGen UID:
1386848
Concept ID:
C1504436
Disease or Syndrome
A pneumatocele is a thin walled, gas-filled space in the lung. It is most frequently caused by acute pneumonia, trauma, or aspiration of hydrocarbon fluid and is usually transient. The mechanism is believed to be a combination of parenchymal necrosis and check-valve airway obstruction. A pneumatocele appears as an approximately round, thin-walled airspace in the lung.
Asthma
MedGen UID:
2109
Concept ID:
C0004096
Disease or Syndrome
Asthma is characterized by increased responsiveness of the tracheobronchial tree to multiple stimuli, leading to narrowing of the air passages with resultant dyspnea, cough, and wheezing.
Chronic mucocutaneous candidiasis
MedGen UID:
2426
Concept ID:
C0006845
Disease or Syndrome
Recurrent or persistent superficial Candida infections of the skin, mucous membranes, and nails.
Atopic eczema
MedGen UID:
41502
Concept ID:
C0011615
Disease or Syndrome
Atopic dermatitis (ATOD), also known as eczema, is a common chronic pruritic inflammatory skin disease with a strong genetic component. Onset typically occurs during the first 2 years of life (review by Soderhall et al., 2007). Genetic Heterogeneity of Atopic Dermatitis Many inflammatory diseases, such as atopic eczema, are genetically complex, with multiple alleles at several loci thought to be involved in their pathogenesis. Several susceptibility loci for atopic dermatitis have been identified: ATOD1 on chromosome 3q21, ATOD2 (605803) on chromosome 1q21, ATOD3 (605804) on chromosome 20p, ATOD4 (605805) on chromosome 17q25.3, ATOD5 (603165) on chromosome 13q12-q14, ATOD6 (605845) on chromosome 5q31-q33, ATOD7 (613064) on chromosome 11q13.5, ATOD8 (613518) on chromosome 4q22.1, and ATOD9 (613519) on chromosome 3p24.
