Variant summary
Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4
The NM_012448.4(STAT5B):c.2018G>A(p.Arg673Gln) variant causes a missense change. The variant allele was found at a frequency of 0.0000031 in 1,613,814 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R673W) has been classified as Uncertain significance.

Growth hormone insensitivity with immune dysregulation 1, autosomal recessive Uncertain:1
This variant is present in population databases (rs776285574, ExAC 0.001%). This variant has not been reported in the literature in individuals with STAT5B-related disease. 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. Algorithms 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. 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.
