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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), STAT5B. . Gene score misZ 3.9952 (greater than the threshold 3.09). Trascript score misZ 5.1164 (greater than threshold 3.09). GenCC has associacion of gene with growth hormone insensitivity syndrome with immune dysregulation, growth hormone insensitivity with immune dysregulation 1, autosomal recessive, growth hormone insensitivity syndrome with immune dysregulation 2, autosomal dominant.

BP4

Computational evidence support a benign effect (MetaRNN=0.3091318).

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 775 of the STAT5B protein (p.Arg775Gln). This variant is present in population databases (rs138115420, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with STAT5B-related conditions. ClinVar contains an entry for this variant (Variation ID: 1439450). 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). -
