It is caused by the lack of UBE3A protein expression, which is an E3-ubiquitin ligase. Despite AS equalprevalence in males and females, not much data on how sex affects the syndrome was reported. In the herein study, we thoroughlycharacterized many behavioral phenotypes of AS mice. The behavioral data acquired was analyzed with respect to sex. Inaddition, we generated a new mRNA sequencing dataset. We analyzed the coding transcriptome expression profiles with respectto the effects of genotype and sex observed in the behavioral phenotypes. We identified several neurobehavioral aspects,especially sensory perception, where AS mice either lack the male-to-female differences observed in wild-type littermates oreven show opposed differences. However, motor phenotypes did not show male-to-female variation between wild-type (WT) andAS mice. In addition, by utilizing the mRNA sequencing, we identified genes and isoforms with expression profiles that mirrorthe sensory perception results. These genes are differentially regulated in the two sexes with inverse expression profiles in ASmice compared to WT littermates. Some of...
