Abstract:
Objective:To carry out variant analysis for a fetus suspected with harlequin ichthyosis (HI).
Methods:Whole exome sequencing (WES) was employed to detect potential variant in the fetus. Suspected variant was validated by Sanger sequencing.
Results:A homozygous missense variant c. 6858delT (p.F2286fs) was detected in the fetus, for which both parents were heterozygous carriers. Pathological analysis confirmed the diagnosis of HI.
Conclusion:The c. 6858delT variant of the ABCA12 gene probably underlies the disease in the fetus.
