Immunodeficiency 94 with autoinflammation and dysmorphic facies(IMD94)

MedGen UID:
1802872
Concept ID:
C5676918
Disease or Syndrome
Synonym: IMD94
 
Gene (location): IL6ST (5q11.2)
 
Monarch Initiative: MONDO:0030681
OMIM®: 619750

Definition

Immunodeficiency-94 with autoinflammation and dysmorphic facies (IMD94) is a systemic immunologic disorder with onset in early infancy. Primary features include lymphadenopathy, autoinflammation, immunodeficiency with hypogammaglobulinemia, and dysmorphic facial features. Intellectual development is normal and serum IgE is not elevated. The disease results from constitutive activation of the IL6 signaling cascade, resulting in immune dysregulation and a hyperinflammatory state (summary by Materna-Kiryluk et al., 2021). [from OMIM]

Clinical features

From HPO
Fibroma
MedGen UID:
42016
Concept ID:
C0016045
Neoplastic Process
Benign tumors that are composed of fibrous or connective tissue. They can grow in all organs, arising from mesenchyme tissue. The term "fibroblastic" or "fibromatous" is used to describe tumors of the fibrous connective tissue. When the term fibroma is used without modifier, it is usually considered benign, with the term fibrosarcoma reserved for malignant tumors.
Cubitus valgus
MedGen UID:
490152
Concept ID:
C0158465
Acquired Abnormality
Abnormal positioning in which the elbows are turned out.
Mitral regurgitation
MedGen UID:
7670
Concept ID:
C0026266
Disease or Syndrome
An abnormality of the mitral valve characterized by insufficiency or incompetence of the mitral valve resulting in retrograde leaking of blood through the mitral valve upon ventricular contraction.
Short stature
MedGen UID:
87607
Concept ID:
C0349588
Finding
A height below that which is expected according to age and gender norms. Although there is no universally accepted definition of short stature, many refer to "short stature" as height more than 2 standard deviations below the mean for age and gender (or below the 3rd percentile for age and gender dependent norms).
Hepatosplenomegaly
MedGen UID:
9225
Concept ID:
C0019214
Sign or Symptom
Simultaneous enlargement of the liver and spleen.
Low-set ears

C0239234
Congenital Abnormality
Upper insertion of the ear to the scalp below an imaginary horizontal line drawn between the inner canthi of the eye and extending posteriorly to the ear.
Posteriorly rotated ears
MedGen UID:
96566
Concept ID:
C0431478
Congenital Abnormality
A type of abnormal location of the ears in which the position of the ears is characterized by posterior rotation (the superior part of the ears is rotated towards the back of the head, and the inferior part of the ears towards the front).
Microcytic anemia
MedGen UID:
1673948
Concept ID:
C5194182
Disease or Syndrome
A kind of anemia in which the volume of the red blood cells is reduced.
Avascular necrosis
MedGen UID:
10200
Concept ID:
C0027543
Disease or Syndrome
A disease where there is cellular death (necrosis) of bone components due to interruption of the blood supply.
Scoliosis
MedGen UID:
11348
Concept ID:
C0036439
Disease or Syndrome
The presence of an abnormal lateral curvature of the spine.
Pectus carinatum
MedGen UID:
57643
Concept ID:
C0158731
Finding
A deformity of the chest caused by overgrowth of the ribs and characterized by protrusion of the sternum.
Macrocephaly
MedGen UID:
745757
Concept ID:
C2243051
Finding
Occipitofrontal (head) circumference greater than 97th centile compared to appropriate, age matched, sex-matched normal standards. Alternatively, a apparently increased size of the cranium.
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.
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.
Lymphadenopathy
MedGen UID:
96929
Concept ID:
C0497156
Disease or Syndrome
Enlargement (swelling) of a lymph node.
Decreased circulating antibody concentration
MedGen UID:

Concept ID:
C4048270
Finding
An abnormally decreased level of immunoglobulin in blood.
Elevated circulating C-reactive protein concentration
MedGen UID:
892906
Concept ID:
C4023452
Finding
An abnormal elevation of the C-reactive protein level in the blood circulation.
Elevated circulating amyloid A concentration
MedGen UID:
1788190
Concept ID:
C5539521
Finding
The concentration of serum amyloid A in the blood circulation is above the upper limit of normal.
High palate
MedGen UID:
66814
Concept ID:
C0240635
Congenital Abnormality
Height of the palate more than 2 SD above the mean (objective) or palatal height at the level of the first permanent molar more than twice the height of the teeth (subjective).
Mandibular prognathia
MedGen UID:
98316
Concept ID:
C0399526
Finding
Abnormal prominence of the chin related to increased length of the mandible.
Downslanted palpebral fissures

98391
Concept ID:
C0423110
Finding
The palpebral fissure inclination is more than two standard deviations below the mean.

MedGen UID:
99267
Concept ID:
C0521525
Finding
Diminished length of the neck.
Depressed nasal bridge
MedGen UID:
373112
Concept ID:
C1836542
Finding
Posterior positioning of the nasal root in relation to the overall facial profile for age.
Prominent forehead
MedGen UID:
373291
Concept ID:
C1837260
Finding
Forward prominence of the entire forehead, due to protrusion of the frontal bone.
Deep philtrum

Finding
Accentuated, prominent philtral ridges giving rise to an exaggerated groove in the midline between the nasal base and upper vermillion border.
Anteverted nares
MedGen UID:
326648
Concept ID:
C1840077
Finding
Anteriorly-facing nostrils viewed with the head in the Frankfurt horizontal and the eyes of the observer level with the eyes of the subject. This gives the appearance of an upturned nose (upturned nasal tip).

Although hypertelorism means an excessive distance between any paired organs (e.g., the nipples), the use of the word has come to be confined to ocular hypertelorism. Hypertelorism occurs as an isolated feature and is also a feature of many syndromes, e.g., Opitz G syndrome (see 300000), Greig cephalopolysyndactyly (175700), and Noonan syndrome (163950) (summary by Cohen et al., 1995).
