Genes affected
STAT5B (HGNC:11367): (signal transducer and activator of transcription 5B) The protein encoded by this gene is a member of the STAT family of transcription factors. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. This protein mediates the signal transduction triggered by various cell ligands, such as IL2, IL4, CSF1, and different growth hormones. It has been shown to be involved in diverse biological processes, such as TCR signaling, apoptosis, adult mammary gland development, and sexual dimorphism of liver gene expression. This gene was found to fuse to retinoic acid receptor-alpha (RARA) gene in a small subset of acute promyelocytic leukemias (APLL). The dysregulation of the signaling pathways mediated by this protein may be the cause of the APLL. [provided by RefSeq, Jul 2008]

Submissions by phenotype

Growth hormone insensitivity with immune dysregulation 1, autosomal recessive Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeFeb 01, 2018Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with STAT5B-related disease. This variant is present in population databases (rs776285574, ExAC 0.001%). This sequence change replaces arginine with glutamine at codon 673 of the STAT5B protein (p.Arg673Gln). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and glutamine. -
