Clinical Description OMIM Dobbs et al. (2007) reported a 15-year-old female patient of Georgian (South Caucasus) descent living in Austria who had recurrent infections, hypogammaglobulinemia, and less than 2% circulating CD19-positive B cells. The patient had been well until 5 months ...
Molecular genetics OMIM In a 15-year-old female patient with early onset of infections, hypogammaglobulinemia, and markedly reduced B cells (AGM6), Dobbs et al. (2007) identified a a homozygous mutation (G137S; 147245.0001) in the CD79B gene. The substitution occurred adjacent to the ...
