Genes affected

PIAS1 (HGNC:2752): (protein inhibitor of activated STAT 1) This gene encodes a member of the protein inhibitor of activated STAT (PIAS) family. PIAS proteins function as SUMO E3 ligases and play important roles in many cellular processes by mediating the sumoylation of target proteins. This protein plays a central role as a transcriptional coregulator of numerous cellular pathways includign the STAT1 and nuclear factor kappaB pathways. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Mar 2016]

Invitae

Sep 25, 2022

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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt PIAS1 protein function. This variant has not been reported in the literature in individuals affected with PIAS1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.007%). This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 103 of the PIAS1 protein (p.Pro103Thr). -
