Deletion of STAT1 from GABAergic inhibitory neurons resulted in deficits in social behavior in mice as measured by the three-chamber social task (Filiano et al., 2016). A novel and predicted damaging de novo missense variant in this gene was identified in an ASD proband from the Simons Simplex Collection (Iossifov et al., 2014).
Molecular Function
This gene encodes a signal transducer and transcription activator that mediates cellular responses to interferons (IFNs), cytokine KITLG/SCF and other cytokines and other growth factors.

Stat1 conditional knockout from gabaergic neurons causes mice to be impaired in socialibility, Stat1 homozygous null mice have impaired growth and are susceptible to viral diseases.

Model Type:
Genetic
Model Genotype:
Homozygous
Mutation:
Conditional deletion of first two untranslated exons and the first translated exon of the Stat1 gene using Cx3cr1-cre, from all cells of myeloid origin including microglia that are known to express Ifn-gamma receptor, as the importance of Ifn-gamma signaling in various neuronal types was being studied
Allele Type: Conditional loss-of-function
Strain of Origin: Genetic Background: C57Bl/6
ES Cell Line: Mutant ES Cell Line: Model Source: JAX

Description: Loss of stat1 from gabaergic inibitory neurons, attentuating ifn-gamma signaling in these neurons, impairs social behavior as the conditional knockouts show reduced preference to social stimulus over object
Exp Paradigm: NA
