Typical X linked agammaglobulinaemia (XLA) is characterised by absence of immunoglobulin production and lack of mature B cells. The gene responsible for XLA has recently been identified, and codes for a B cell tyrosine kinase, BTK. A family affected by a B cell immunodeficiency, which is less severe than classical XLA, is described but they had a pedigree suggestive of X linked inheritance. Demonstration of a mutation in the BTK gene confirms that this is a mild form of XLA.
典型的X连锁无丙种球蛋白血症(XLA)的特征是缺乏免疫球蛋白产生以及缺乏成熟B细胞。导致XLA的基因最近已被确定,它编码一种B细胞酪氨酸激酶,即BTK。本文描述了一个受B细胞免疫缺陷影响的家族,其症状比经典XLA轻,但其家系提示X连锁遗传。BTK基因突变的证实表明这是一种轻度形式的XLA。
