Objectives: To present a family in which it was possible to perform prenatal diagnosis for the recessively inherited muscle-eye-brain disease (MEB) using linkage analysis.
Methods: Linkage analysis and direct sequencing of the POMGNT1 gene were carried out in a Turkish MEB family with one affected individual. Fetal DNA was obtained from an ongoing pregnancy by chorionic villus sampling (CVS).
Results: Both linkage analysis of the POMGNT1/1p32-p34 region and direct sequencing for the novel familial mutation (R605H) demonstrated that the fetus did not have MEB.
Conclusion: We report the first case of prenatal diagnosis in MEB by molecular genetic analysis.
