Variant summary

Our verdict is Benign. The variant received -15 ACMG points: 1P and 16B. PP3BP6_Very_StrongBA1

The NM_005419.4(STAT2):c.1343C>T(p.Thr448Met) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00416 in 1,614,200 control chromosomes in the GnomAD database, including 366 homozygotes. In-silico tool predicts a benign outcome for this variant. 2/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as Benign (★★). Synonymous variant affecting the same amino acid position (i.e. T448T) has been classified as Uncertain significance.

Genes affected

STAT2 (HGNC:11363): (signal transducer and activator of transcription 2) The protein encoded by this gene is a member of the STAT protein family. 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. In response to interferon (IFN), this protein forms a complex with STAT1 and IFN regulatory factor family protein p48 (ISGF3G), in which this protein acts as a transactivator, but lacks the ability to bind DNA directly. The protein mediates innate antiviral activity. Mutations in this gene result in Immunodeficiency 44. [provided by RefSeq, Aug 2020]
