Primary

MeasureTime frame
The identification and classification of EPHB4 variants of uncertain significance (VUS) in 20 pediatric patients (100% of cohort) with idiopathic toe walking (ITW). Measured by: Frequency of Pathogenic (P), likely pathogenic (LP), and variants of uncertain significance (VUS) in EPHB4 gene using NGS panel testing.
