Study Description
Name: Help
Genetic Studies of Human Developmental Disorders
Test purpose: Help
Contribute to generalizable knowledge
Description: Help
Screening of genes known to be involved in eye development will be performed by exome/genome and/or Sanger sequencing. If no mutation is found, data will be reviewed for novel gene identification and we will continue to screen samples for mutations in other genes characterized as research progresses. Referring providers will … View more
