[Saethre-Chotzen syndrome: a case report].

Abstract

The Saethre-Chotzen syndrome is a craniofacial malformation syndrome characterized by synostosis of coronal sutures and limb anomalies. The estimated prevalence of this syndrome is 1 in 25 000-50 000 live births. We present a case report of a neonate, without relevant family history, who presented craniofacial alterations at birth. Given the phenotypic features, a cranial computed tomography scan was performed, showing partial fusion of the coronal suture, evidencing the presence Síndrome de Saethre-Chotzen: a propósito de un caso Saethre-Chotzen syndrome: a case report of wormian bones in the metopic and right lambdoid location. With the clinical suspicion of craniofacial malformation syndrome, an analysis of the directed exome was requested confirming that the patient is a heterozygous carrier of the pathogenic variant c.415C>A, which induces a change of proline to threonine at position 139 of the TWIST1 gene, responsible for Saethre-Chotzen syndrome. The presence of wormian bones, a finding not described so far in the literature, extends the well-known phenotypic variability of this syndrome.
