Bruton agammaglobulinemia, also known as X-linked agammaglobulinemia (XLA) or Bruton’s agammaglobulinemia, is an inherited immunodeficiency disorder. It is characterized by the absence of mature B cells which in turn leads to severe antibody deficiency and recurrent infections.

Common variable immune deficiency (CVID) is a type of primary immunodeficiency, which is defined as an immune system dysfunction typically caused by a mutation in a gene or genes. The World Health Organization (WHO) recognizes more than 400 primary immunodeficiencies ranging from relatively common to quite rare.

How is XLA inherited?
X-linked inheritance pattern with carrier mother X-linked agammaglobulinemia is caused by a genetic mutation. People with the condition can’t produce antibodies that fight infection. About 40% of people with the condition have a family member who has it.
Can females have XLA?
Most individuals lead a normal life. However, approximately 10% develop significant infections despite appropriate therapy and many have chronic pulmonary changes [Quartier et al 1999]. Heterozygous females. A single female with XLA has been reported.
How is XLA diagnosed?
The diagnosis of XLA can be confirmed by demonstrating the absence of BTK protein in monocytes or platelets or by the detection of a mutation in BTK in DNA. Almost every family has a different mutation in BTK; however, members of the same family usually have the same mutation.
What is Vid illness?
Common variable immunodeficiency (CVID) is an immune system disorder that causes you to have low levels of the proteins that help fight infections. If you have CVID , you’ll likely have repeated infections in your ears, sinuses and respiratory system.

Definition. A reduction in the circulating levels of all the major classes of immunoglobulin. is characterized by profound decreases in all classes of immunoglobulin with an absence of circulating B lymphocytes. [ from HPO]
What is the life expectancy of someone with Hypogammaglobulinemia?
The life expectancy of CVID patients has considerably improved over the past 30 years [5, 63], from initially 12 years to currently over 50 years [3]. Reduced survival was significantly associated with age at diagnosis, lower baseline IgG, higher IgM and fewer peripheral B cells.
What is Osteochondrodysplasia?
Osteochondrodysplasias are a group of rare hereditary disorders of connective tissue, bone, or cartilage that cause the skeleton to develop abnormally. In osteochondrodysplasias, the growth and development of bone.
What is Paramyotonia?
Paramyotonia congenita (PMC) is a rare non-progressive genetic disorder that affects the skeletal muscles. The disorder typically begins in infancy or early childhood. Affected individuals experience spells of muscle stiffness or when the muscles do not relax after contracting (myotonia).
Is myotonia congenita a form of muscular dystrophy?
Myotonia congenita is a congenital neuromuscular channelopathy that affects skeletal muscles (muscles used for movement). It is a genetic disorder. …
| Myotonia congenita | |
|---|---|
| Causes | Genetic, CLCN1 mutations |
| Diagnostic method | Clinical, genetic testing |
| Differential diagnosis | Myotonic dystrophy, Paramyotonia congenita |
What is myotonic Chondrodystrophy?

What is stuve Wiedemann syndrome?
Stuve Wiedemann syndrome (STWS) is rare genetic and disorder that has been diagnosed in very few patients. It is characterized by short stature, bowing of the long bones of the arms and legs (campomelia), and fingers or toes that are permanently flexed (camptodactyly) outward away from the thumb (ulnar deviation).
What is Trident hand?
Definition. A hand in which the fingers are of nearly equal length and deflected at the first interphalangeal joint, so as to give a forklike shape consisting of separation of the first and second as well as the third and fourth digits. [ from HPO]

What causes Barber Say syndrome?
Genetics. Multiple cases of parent-to-child transmission suggest that Barber-Say syndrome exhibits autosomal dominant inheritance. Exome sequencing and expression studies have shown that BSS is caused by mutations in the TWIST2 gene that affect a highly conserved residue of TWIST2 (twist-related protein 2).
