STAT5B (P51692) variants and mutations

STAT5B (also known as P51692) is a human protein-coding gene encoding a signal transducer and activator of transcription 5B protein. It carries signals from growth hormone and multiple cytokines into transcriptional programs controlling growth, immune regulation, and lymphocyte survival. Loss-of-function variants cause growth-hormone insensitivity with immune dysregulation, whereas activating somatic variants can drive hematologic malignancy. This analysis covers 841 STAT5B variants and mutations. Of these, 74% have computational variant effect predictions. Disease context includes growth hormone insensitivity with immune dysregulation 1, autosomal recessive, growth hormone insensitivity syndrome with immune dysregulation 2, autosomal dom, and cancer. Example STAT5B variants include M1?, A2T, and V3A.
