Pediatria i Medycyna Rodzinna. Immunodeficiency in children with dysmorphic disorders. Ataxia telangiectasia, Nijmegen breakage syndrome and DiGeorge syndrome are congenital disorders belonging to the category of primary immunodeficiencies.

They are characterised by remittent infections as well as predisposition to cancer and autoimmune diseases. An important sign of ataxia telangiectasia and Nijmegen breakage syndrome is an increased sensitivity of cells to ionising radiation, while DiGeorge syndrome is additionally characterised by heart defects and endocrine disorders.

What all these diseases have in common are dysmorphic features of different severity, which complement the atxksja picture. The signs and symptoms of the diseases may be inconclusive, they appear at various stages of life and their course is unique for every individual. The aim of the study was teleanfiektazja present the characteristics of each syndrome while drawing special attention to dysmorphic features occurring in patients. It is important for doctors to be able to diagnose characteristic disorders of the phenotype and immune system and to match them to the right genetic syndrome.

Despite atakxja fact that these syndromes are rare and incurable disorders, fast and accurate diagnosis gives patients a chance for telewngiektazja improved quality and length of life. The treatment is only symptomatic, but proper prevention can help to avoid the development of a cancer.

Ataxia-telangiectasia is the association of severe combined immunodeficiency affecting mainly the humoral immune response with progressive cerebellar ataxia.

ataxia telangiectasia – Wikidata

It is characterised by neurological signs, telangiectasias, increased susceptibility to infections and a higher risk of cancer. The severity of the neurological, immune system and pulmonary manifestations varies widely between patients. Onset usually occurs between 1 and 2 years of age with abnormal head movements and loss of balance, followed by slurred speech and abnormal eye movements. Poor coordination and trembling of the extremities may appear towards years of age and worsen progressively.

Choreoathetosis is quite common. In the majority of cases, intelligence is normal: Cutaneomucosal telangiectasias appear between 3 and 6 years of age, or during adolescence. The immunodeficiency causes repeated sinus and lung infections, and the latter may cause bronchiectasis. Growth delay is also fairly frequent. This gene is expressed ubiquitously and encodes a protein kinase playing a key role in the control of double-strand-break DSB DNA repair, notably in the Purkinje cells of the cerebellum and in cerebral, cutaneous and conjunctival endothelial cells.

Establishing the clinical diagnosis early in the disease course is problematic but quasi-constant increases in serum alpha-foetoprotein AFP levels and cytogenetic analysis may help confirm the diagnosis 7;14 translocations.

Molecular diagnosis is sometimes necessary. The differential diagnosis should include Ataxia – oculomotor apraxia, types 1 and2 see these telangiektazja. Prenatal diagnosis is possible once at least one inactivating ATM gene mutation has been identified in the index case. Management is symptomatic and involves physiotherapy, speech therapy and treatment of the infection and pulmonary complications. Beta-blockers may reduce trembling and improve performance of fine movements.
