Prenatal diagnosis of X-linked myopathy associated with a VMA21 gene mutation afforded through a novel targeted exome sequencing strategy applied in fetuses with abnormal ultrasound findings.

Fetal malformations detected through routine prenatal ultrasound examination comprise a heterogeneous group potentially associated with genetic disorders where the underlying cause is difficult to establish. We present the prenatal diagnosis of a rare X-linked myopathy involving a new VMA21 gene mutation, detected through a novel prenatal exome sequencing-based approach.
