Study summary

This study will seek to determine if whole genome sequencing (WGS) improves diagnostic rates, and outcomes for congenital diarrhea and enteropathy (CODE) patients. The investigator will enroll 180 patients in a randomized controlled study to either WGS or whole exome sequencing (WES). This study is designed to evaluate whether CODE patients would benefit from WGS guided precision medicine.

    Time frame: Within approximately 60 days of enrollment

Secondary outcomes

  1. Number of patients receiving precision medicine guided by sequencing results

    Rate of application of precision medicine suggested by the results of WGS or WES.

    Time frame: Within approximately 60 days of enrollment

  2. Mortality of patients

    Mortality of patients after WGS and WES

    Time frame: Within approximately 1 year of enrollment

  3. Rate of parental satisfaction with sequencing

    Parental satisfaction with decision to pursue sequencing based on questionnaire survey

    Time frame: Within one week of patient enrollment

  4. Number of parents who are available for trio sequencing

    Number of subjects in which both parents are available for trio sequencing

    Time frame: Within one week of patient enrollment
