  Purpose

The goal of this study is to identify and characterize the genetic loci causing idiopathic talipes equinovarus (clubfoot).

The hypothesis is that a few genes account for a substantial fraction of ITEV and that these genes can be identified in defined populations. Towards this goal, in preliminary studies, Dr. Hecht's group has identified two genes, NAT2 and CASP10, which demonstrate evidence for linkage and association to ITEV.


Condition

Enrollment: 370
Study Start Date: August 2004
Study Completion Date: August 2013
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Detailed Description:

Blood Collection: For this study, the investigators need to obtain blood samples from members of families in which clubfoot has occurred; more specifically, blood samples from the affected child and both parents. DNA will be extracted from blood samples. The DNA will then be tested to look for genetic factors that cause clubfoot.

Study Questionnaires: As well as the blood samples, the investigators have a short questionnaire for the mother of the child with clubfoot to complete.

  Eligibility

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population

One family member, usually child, must have clubfoot.

Criteria

Inclusion Criteria:

  • One family member, usually child, must have clubfoot
