Labcorp Genetics (formerly Invitae), Labcorp RCV001943359 SCV002182295 uncertain significance Immunodeficiency 31B; Autoimmune enteropathy and endocrinopathy - susceptibility to chronic infections syndrome; Mendelian susceptibility to mycobacterial diseases due to partial STAT1 deficiency 2023-11-22 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 446 of the STAT1 protein (p.Ile446Val). This variant is present in population databases (no rsID available, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with STAT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1413109). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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.
