Clinical case of primary immunodeficiency: X-linked agammaglobulinemia

Abstract

Aclinical case ofprimary immunodeficiency state (PIDS) is described: X-linked agammaglobulinemia in the boy of 8 years old. The results of molecular genetic studies: gene btk (ex 1-19) genome version GRCh38.p5, transcript version ENST00000308731 single nucleotide substitution identified с.1027С > Т in homozygous state leading to premature stop codon p.Gln343Ter (p.Q343*). The presented clinical case reflects the low alertness of pediatricians for PIDS. At the same time, a delay in diagnosis and prescription of treatment aggravates the prognosis of the disease course and reduces the quality of the patient life.
