Diagnosis of a fetus with X-linked hydrocephalus due to mutation of L1CAM gene / 中华医学遗传学杂志

ABSTRACT

OBJECTIVE@#To explore the genetic basis for a case of recurrent fetal congenital hydrocephalus.@*METHODS@#Next-generation sequencing was carried out for the fetus, the gravida and two of her sisters.@*RESULTS@#The fetus was found to harbor a c.1765T>C (p.Tyr589His) mutation in exon 14 of the L1CAM gene, which was derived from the gravida.@*CONCLUSION@#Male fetuses with recurrent hydrocephalus should be subjected to testing of the L1CAM gene to facilitate genetic counseling and prenatal diagnosis.
