Description

This sequence change creates a premature translational stop signal (p.Trp588*) in the BTK gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BTK are known to be pathogenic (PMID: 15661032, 16862044, 19419768). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with agammaglobulinemia (PMID: 9106525, 9545398). ClinVar contains an entry for this variant (Variation ID: 645226). For these reasons, this variant has been classified as Pathogenic.
