Brief Summary: Background

Uveal coloboma is a congenital eye malformation It is thought to be a genetic condition But it might have environmental causes as well Researchers want to study the mothers of children with coloboma They will use parts of the National Birth Defects Prevention Study NBDPS Mother Questionnaire NBDPS was a large study of birth defects It collected data from 1997 to 2011 Researchers will use NBDPS and NIH data as well as the new survey to produce data that can serve as a basis for further study

Objective

To explore maternal factors and exposures during the first trimester of pregnancy as potential causes of uveal coloboma and to correlate exposure data to clinical data from affected children

Eligibility

Mothers of probands with coloboma who have taken part in NIH study 06-EI-0230 04-EI-0039 or 13-EI-0049

Design

This is a hybrid study It will use existing data from NBDPS and NIH studies It will also use NBDPS for a new survey of mothers of children with coloboma

Participants will take the survey by phone Their pregnancy records may be reviewed They will be asked about

Important dates

Health and medicines

Tobacco alcohol and substance use

Parents occupations

Family demographics

The survey will take 1 hour or less to complete

Some data were obtained in past NIH studies These data are largely from children Some family data may be used as well For example eye exam data gene test results and family history of coloboma may be used If a participant did not consent to the future use of their data then their data will not be used

Data will be stored in a secure NIH database

Detailed Description: Study Description

This evaluation of potential environmental causes of coloboma explores the experiences of a large cohort of mothers of children with uveal coloboma using portions of the National Birth Defects Prevention Study NBDPS Mother Questionnaire It is postulated that maternal hypothyroidism and in utero alcohol exposure are found at higher rates in this cohort than in rates found in the general population The goal is to produce descriptive statistic that could serve as a basis for further epidemiologic studies

Objectives

The primary objective is to explore maternal factors and exposures during the first trimester of pregnancy as potential causes of uveal coloboma and to correlate these exposures with the clinical presentation of the affected childchildren
