Uncovering Low-Level Maternal Gonosomal Mosaicism in X-Linked Agammaglobulinemia: Implications for Genetic Counseling

[Dermatomyositis-like syndrome in x-linked agammaglobulinemia].

Primary immunodeficiencies (PIDs) encompass more than 250 different pathological conditions. X-linked agammaglobulinemia (XLA) has been occasionally associated with cutaneous and muscular manifestations resembling dermatomyositis, often termed dermatomyositis-like syndrome (DLS). This syndrome has been associated with cutaneous, muscular and central nervous system manifestations, accompanying a...

Genotype/phenotype correlations in X-linked agammaglobulinemia.

No clear genotype/phenotype correlations have been established in patients with X-linked agammaglobulinemia (XLA). To determine if the specific mutation in Btk might be one of the factors that influences the severity of disease or if polymorphic variants in Tec, a cytoplasmic tyrosine kinase that might substitute for Btk, could contribute to the clinical phenotype, we examined the age at diagno...

neutropenia associated with x-linked agammaglobulinemia

x-linked agammaglobulinemia (xla) is a hereditary immunodeficiency, characterized by an early onset of recurrent bacterial infections, hypogammaglobulinemia and markedly reduced b lymphocytes number. in order to determine the association of neutropenia among iranian patients with xla, hospital records of 30 patients with confirmed xla in children medical center hospital, were reviewed. eight ou...
