Severe combined immunodeficiency is a large clinically heterogeneous group of disorders caused by a defect in the development of humoral or cellular immune responses. At least 13 genes are known to be involved in the pathophysiology of the disease and the mutation spectrum in SCID has been well documented. Mutations of the recombination-activating genes RAG(More)
Dystrophic epidermolysis bullosa simplex (DEB) is a phenotypically diverse inherited skin fragility disorder. It is majorly manifested by appearance of epidermal bullae upon friction caused either by physical or environmental trauma.

Syndromes of mineralocorticoid excess (SME) are closely related clinical manifestations occurring within a specific set of diseases. Overlapping clinical manifestations of such syndromes often create a dilemma in accurate diagnosis, which is crucial for disease surveillance and management especially in rare genetic disorders. Here we demonstrate the use of(More)
X-linked agammaglobulinemia (XLA) is an extremely rare inherited primary immunodeficiency characterized by recurrent bacterial infections, decrease in number of mature B cells and low serum immunoglobulins. XLA is caused by mutations in the gene encoding Bruton's tyrosine kinase. We report a case of a young Indian boy suspected to have XLA.(More)
