BTK gene full mutation analysis in Blood or Tissue by Sequencing
Active
Term Description
Full gene sequence analysis of the BTK gene to identify a pathogenic mutations and confirm a diagnosis of X-linked agammaglobulinemia (XLA) in male patients with a clinical history and laboratory findings (e.g. recurrent sinopulmonary infections, profound hypogammaglobulinemia, and less than 1% peripheral B cells, and with or without abnormal Bruton tyrosine kinase (Btk) protein expression by flow cytometry). For female relatives of male XLA patients who do not demonstrate carrier phenotype by Btk flow cytometry, this test may also be performed.

LP150045-5 Sequencing
Sequencing is a method used to determine the sequence of individual genes, larger genetic regions (i.e. clusters of genes or operons), full chromosomes or entire genomes. Historically, most sequencing has been performed using the chain termination method developed by Frederick Sanger in 1977. PMID: 271968 Sequencing technologies have improved dramatically, making them cheaper, faster, and more accurate. Next-generation sequencing (NGS), also known as high-throughput sequencing, deep sequencing, and second-generation sequencing, is a type of technology that uses parallel sequencing of multiple small fragments of DNA to determine sequence. This "high-throughput" technology has increased the speed and amount of DNA sequenced at a significantly reduced cost. PMID: 18576944 Several NGS platforms (ie, sequencing instruments and associated reagents) have been developed. Third-generation sequencing is another methodology currently under development that uses parallel sequencing similar to NGS. In contrast to NGS, third-generation sequencing uses single DNA molecules rather than amplified DNA as a template. PMID: 20858600

LP33144-4 BTK gene
The BTK gene (Bruton agammaglobulinemia tyrosine kinase) [HGNC Gene ID:1133] is located on chromosome Xq21.33-q22. The protein encoded by this gene plays a crucial role in B-cell development. Mutations in this gene cause X-linked agammaglobulinemia type 1, which is an immunodeficiency characterized by the failure to produce mature B lymphocytes, and associated with a failure of Ig heavy chain rearrangement. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2013] [NCBI Gene ID:695]

LP33144-4 BTK gene
Patients with chronic lymphocytic leukemia (CLL) with disease progression treated with ibrutinib has been attributed to histologic transformation or acquired mutations in BTK and PLCG2 genes. PMID: 28049639
