Study on Prenatal Diagnosis and Closed-loop Management System of Congenital Talipes Equinovarus

The study intends to establish a closed-loop management from prenatal to postnatal through prospective cohort, and comprehensively utilize ultrasound and MRI technology to establish a prenatal diagnosis and evaluation system for congenital talipes equinovarus. On the basis of existing genetic testing, further use of whole-exome sequencing and other genomic methods to explore possible pathogenic genes and loci, and clarify the pathogenic mechanism of congenital talipes equinovarus. Therefore, congenital talipes equinovarus can improve its diagnosis and treatment capacity, reduce the disability rate related to congenital talipes equinovarus, and prevent it well.
