Across the last four days of gestation, Pitx3 mutants showed significantly increased latencies to exhibit Facial Wiping response to oral/tactile stimulation as compared to both heterozygous and C57BL/6J controls. These findings provide evidence that the primary fetal neurobehavioral deficit of the Pitx3 mutation is akinesia related to nigrostriatal damage. These results further demonstrate the sensitivity of fetal neurobehavioral assessments in the detection of emerging neural dysfunction, suggesting utility for prenatal diagnosis.
