Infantile Systemic Hyalinosis

Infantile systemic hyalinosis (ISH) is a rare and devastating genetic disorder that affects infants. It is characterized by the abnormal accumulation of a substance called hyaline in various tissues and organs throughout the body. This build-up of hyaline leads to a wide range of symptoms and can ultimately result in a shortened lifespan for affected individuals. Infantile systemic hyalinosis is an autosomal recessive disorder, which means that it occurs when both parents carry a mutated gene and pass it on to their child. The specific gene associated with ISH is called ANTXR2. When a child inherits two copies of the mutated ANTXR2 gene, it leads to the development of ISH.

Infantile systemic hyalinosis (ISH) is an extremely rare autosomal recessive genetic disorder that primarily affects infants and young children. It is characterized by the abnormal accumulation of a substance called hyaline in various tissues and organs throughout the body. ISH can cause a wide range of symptoms, which can vary in severity from person to person.

Types

Types of Infantile Systemic Hyalinosis: Infantile systemic hyalinosis has two primary types, namely classical infantile systemic hyalinosis and juvenile systemic hyalinosis. Let’s explore each type in detail:

Classical Infantile Systemic Hyalinosis: This is the most common form of ISH and typically manifests within the first few months of life. The major clinical features of classical infantile systemic hyalinosis include:

a. Skin Manifestations: Infants with ISH develop thickened, hardened skin with characteristic plaques and nodules. The skin is typically tight and leathery, limiting joint movement.

b. Joint Contractures: Restricted movement due to joint contractures is a common feature of ISH. This can lead to a limited range of motion and joint deformities.

c. Gastrointestinal Involvement: Infants with ISH often experience severe gastrointestinal problems, such as chronic diarrhea, malabsorption, and failure to thrive.

d. Respiratory Complications: Respiratory distress is a significant concern in ISH. Infants may have difficulty breathing due to the accumulation of hyaline in the respiratory system.

Juvenile Systemic Hyalinosis: Juvenile systemic hyalinosis is a more severe and progressive form of ISH that typically presents in early childhood or infancy. The distinguishing features of this type include:

a. Progressive Musculoskeletal Involvement: Children with juvenile systemic hyalinosis experience progressive joint stiffness and contractures, leading to severe restriction of movement and skeletal deformities.

b. Cardiac Involvement: Cardiac complications, such as cardiomyopathy (weakening of the heart muscle), may occur in juvenile systemic hyalinosis, further contributing to the severity of the condition.

c. Pulmonary Complications: Similar to classical ISH, respiratory problems, including breathing difficulties and recurrent respiratory infections, are common in this type.

ANTXR2-Related Infantile Systemic Hyalinosis: This type of infantile systemic hyalinosis is caused by mutations in the ANTXR2 gene. The ANTXR2 protein is responsible for maintaining the integrity of the extracellular matrix, a network of proteins and other substances that provide structural support to various tissues in the body. Mutations in the ANTXR2 gene disrupt the normal function of this protein, leading to the accumulation of hyaline.
CMG2-Related Infantile Systemic Hyalinosis: CMG2-related infantile systemic hyalinosis is caused by mutations in the CMG2 gene. The CMG2 protein plays a crucial role in regulating cell growth and survival. When mutations occur in the CMG2 gene, it results in the abnormal accumulation of hyaline in different tissues.

Causes

Comprehensive overview of the known causes of infantile systemic hyalinosis, explaining each cause in simple terms.

Mutation in the ANTXR2 gene: The ANTXR2 gene provides instructions for making a protein called anthrax toxin receptor 2. Mutations in this gene can disrupt the normal function of the protein, leading to the development of ISH.
Autosomal recessive inheritance: ISH is inherited in an autosomal recessive manner, meaning that a child must inherit two copies of the mutated gene (one from each parent) to develop the condition.
Consanguinity: Consanguinity, or the marriage between close relatives, increases the risk of ISH as it raises the chances of both parents carrying the same mutation.
Impaired hyaluronan metabolism: Hyaluronan is a type of molecule found in the body’s connective tissues. Impaired metabolism of hyaluronan due to genetic mutations can contribute to the development of ISH.
Deficiency of hyaluronidase enzymes: Hyaluronidase enzymes break down hyaluronan. Deficiencies in these enzymes can lead to the accumulation of hyaluronan, resulting in ISH.
Abnormal cell signaling: Disturbances in the signaling pathways involved in cellular processes can disrupt the normal development and functioning of tissues, contributing to ISH.
Dysfunction of fibroblasts: Fibroblasts are cells that produce connective tissues. Dysfunction of fibroblasts due to genetic mutations can lead to the abnormal accumulation of hyaline.
Impaired lysosomal function: Lysosomes are cellular compartments responsible for breaking down various substances. Impaired lysosomal function can disrupt the breakdown of hyaline, leading to its accumulation in ISH.
Defects in the ECM (extracellular matrix): The ECM provides structural support to cells and tissues. Defects in the ECM can impair normal tissue development and contribute to the pathology of ISH.
Altered tissue repair mechanisms: Genetic mutations can affect the body’s ability to repair damaged tissues, leading to the accumulation of hyaline and the development of ISH.
Aberrant protein aggregation: Mutations in certain genes can cause abnormal aggregation of proteins, leading to the formation of hyaline deposits and the progression of ISH.
Impaired blood vessel formation: The formation of blood vessels during development can be disrupted by genetic mutations, resulting in tissue abnormalities seen in ISH.
Dysfunctional collagen synthesis: Collagen is a vital component of connective tissues. Genetic mutations that affect collagen synthesis can contribute to the pathology of ISH.
Abnormal tissue mineralization: Genetic abnormalities can disrupt the normal process of tissue mineralization, leading to the accumulation of hyaline and the manifestation of ISH.
Defects in glycosaminoglycan metabolism: Glycosaminoglycans are important components of connective tissues. Genetic defects in their metabolism can contribute to the development of ISH.
Impaired cellular transport mechanisms: Genetic mutations can disrupt the transport of essential molecules within cells, affecting normal tissue development and leading to ISH.
Aberrant immune response: Dysregulation of the immune system can contribute to the accumulation of hyaline and the development of ISH.
Disrupted apoptosis: Apoptosis is a natural process of programmed cell death. Dysfunctional apoptosis due to genetic mutations can disrupt tissue development and contribute to ISH.
Abnormal cytokine signaling: Cytokines are small signaling molecules involved in various cellular processes. Abnormal cytokine signaling can disrupt tissue development and contribute to ISH.
Deficiency of essential growth factors: Genetic mutations that lead to a deficiency of crucial growth factors can impair tissue development and contribute to the progression of ISH.
Altered cell adhesion: Genetic abnormalities can disrupt the adhesion between cells, leading to tissue abnormalities observed in ISH.
Impaired cellular communication: Communication between cells is essential for proper tissue development. Genetic mutations that impair cellular communication can contribute to ISH.
Defects in protein folding: Proteins must fold into their proper shapes to function correctly. Genetic mutations can disrupt protein folding, leading to ISH.
Dysfunctional matrix metalloproteinases: Matrix metalloproteinases are enzymes involved in tissue remodeling. Dysfunctional matrix metalloproteinases due to genetic mutations can contribute to ISH.
Altered cell differentiation: Genetic mutations can affect the process of cell differentiation, leading to tissue abnormalities seen in ISH.
Impaired angiogenesis: Angiogenesis is the formation of new blood vessels. Genetic abnormalities can impair angiogenesis, contributing to ISH.
Defects in proteoglycan synthesis: Proteoglycans are important components of the ECM. Genetic defects in their synthesis can contribute to the pathology of ISH.
Oxidative stress: Increased oxidative stress, often due to dysfunctional antioxidant systems, can contribute to tissue damage seen in ISH.
Dysregulation of the cell cycle: The cell cycle regulates cell growth and division. Dysregulation of the cell cycle due to genetic mutations can contribute to ISH.
Mitochondrial dysfunction: Genetic abnormalities affecting mitochondrial function can lead to cellular dysfunction and tissue abnormalities observed in ISH.

Symptoms

Common symptoms associated with ISH

Skin Lesions – Infants with ISH often develop skin lesions, which appear as small, firm bumps on the skin’s surface. These lesions are typically painless and can occur anywhere on the body. Over time, the lesions may increase in size and number, leading to thickening and hardening of the skin. In some cases, the skin lesions can become ulcerated or develop open sores.
Joint Contractures – Joint contractures refer to the permanent tightening of the joints, limiting their range of motion. Infants with ISH may develop joint contractures, particularly in the elbows, knees, and ankles. These contractures can make it difficult for affected individuals to move their limbs freely, leading to restricted mobility.
Growth Failure – Growth failure is a common symptom of ISH. Infants with the condition may experience slow or impaired growth, resulting in a significantly smaller stature compared to their peers. Poor weight gain and short stature are frequently observed, and affected children may not reach typical developmental milestones.
Facial Dysmorphism – Facial dysmorphism refers to abnormal facial features that are characteristic of ISH. Infants may exhibit a distinctive facial appearance, including a small nose, flat nasal bridge, thickened lips, widely spaced eyes, and a prominent forehead. These facial features can be helpful in diagnosing ISH.
Respiratory Problems – ISH can lead to respiratory difficulties, such as recurrent respiratory infections, coughing, and shortness of breath. The accumulation of hyaline in the respiratory tract can cause narrowing of the airways, making breathing more challenging for affected infants.
Gastrointestinal Issues – Infants with ISH may experience various gastrointestinal problems, including difficulty swallowing, vomiting, diarrhea, and poor appetite. These issues can result from the deposition of hyaline in the gastrointestinal tract, leading to impaired functioning.
Cardiac Abnormalities – Cardiac abnormalities, although less common, can occur in ISH. These abnormalities may include thickening of the heart muscle (hypertrophic cardiomyopathy) or structural defects in the heart, which can cause problems with its function. Cardiac complications can contribute to the overall severity of the condition.
Neurological Impairments – Neurological impairments are often observed in ISH. These can range from delayed development and intellectual disability to seizures and muscle stiffness (spasticity). The deposition of hyaline in the central nervous system can disrupt normal brain function, leading to these neurological manifestations.
Liver Dysfunction – Liver dysfunction is another potential symptom of ISH. It can manifest as abnormal liver function tests, an enlarged liver (hepatomegaly), or a buildup of fat within the liver (hepatic steatosis). Liver involvement can contribute to the overall clinical picture of the disorder.
Renal Problems – The kidneys can also be affected by ISH, leading to renal problems. Infants may experience reduced kidney function, proteinuria (the presence of excess protein in urine), or even kidney failure. These renal impairments can further contribute to the multisystem nature of ISH.
Eye Abnormalities – Eye abnormalities are frequently seen in ISH. These can include clouding of the corneas (corneal opacities), glaucoma (increased pressure within the eye), and visual impairment. These ocular manifestations require appropriate monitoring and management.
Musculoskeletal Deformities – Musculoskeletal deformities, such as abnormal curvature of the spine (scoliosis) or fused bones (synostosis), can occur in ISH. These deformities can affect an infant’s posture, mobility, and overall physical well-being.
Dental Issues – Dental abnormalities are common in ISH. These can involve delayed tooth eruption, malformed teeth, and poor dental enamel. Regular dental care is essential to address these issues and maintain oral health.
Delayed Speech Development – Infants with ISH may experience delayed speech development. This can result from a combination of factors, including intellectual disability, muscle stiffness affecting the articulatory organs, and impaired cognitive function.
Hearing Loss – Hearing loss can occur in individuals with ISH. It may be due to structural abnormalities in the ears or damage to the auditory nerves. Regular hearing assessments and appropriate interventions are crucial to address hearing impairments.
Lymphatic Involvement – Lymphatic involvement can manifest as swollen lymph nodes (lymphadenopathy) or lymphedema, which is the accumulation of lymph fluid in tissues, causing swelling. These lymphatic issues can further complicate the clinical presentation of ISH.
Hematological Abnormalities – Infants with ISH may exhibit hematological abnormalities, such as low platelet counts (thrombocytopenia) or anemia. These abnormalities can affect blood clotting and oxygen transport throughout the body.
Metabolic Disturbances – Metabolic disturbances, including abnormal levels of certain substances in the blood, may occur in ISH. These imbalances can affect various organ systems and contribute to the overall disease burden.
Increased Susceptibility to Infections – Due to compromised immune function, infants with ISH are more susceptible to infections, including bacterial, viral, and fungal infections. Frequent and severe infections are commonly observed.
Early Mortality – Infantile systemic hyalinosis is a severe disorder, and sadly, affected infants often have a significantly shortened lifespan. The disease’s multisystem involvement and complications can lead to early mortality, usually within the first few years of life.
