Muenke syndrome
Definitions related to muenke syndrome:
-
A rare autosomal dominant inherited disorder caused by mutations in the FGFR3 gene. It is characterized by premature fusion of cranial bones, resulting in head shape abnormalities, flattened cheekbones, and wide-set eyes.NCI ThesaurusU.S. National Cancer Institute, 2021

Muenke syndrome is defined by the presence of the specific FGFR3 pathogenic variant � c.749C>G � that results in the protein change p.Pro250Arg. Muenke syndrome is characterized by considerable phenotypic variability: features may include coronal synostosis (more often bilateral than unilateral); synostosis of other sutures, all sutures (pan synostosis), or no sutures; or macrocephaly. Bilateral coronal synostosis typically results in brachycephaly (reduced anteroposterior dimension of the skull), although turribrachycephaly (a "tower-shaped" skull) or a cloverleaf skull can be observed. Unilateral coronal synostosis results in anterior plagiocephaly (asymmetry of the skull and face). Other craniofacial findings typically include: temporal bossing; widely spaced eyes, ptosis or proptosis (usually mild); midface retrusion (usually mild); and highly arched palate or cleft lip and palate. Strabismus is common. Other findings can include: hearing loss (in 33%-100% of affected individuals); developmental delay (~33%); epilepsy; intracranial anomalies; intellectual disability; carpal bone and/or tarsal bone fusions; brachydactyly, broad toes, broad thumbs, and/or clinodactyly; and radiographic findings of thimble-like (short and broad) middle phalanges and/or cone-shaped epiphyses. Phenotypic variability is considerable even within the same family. Of note, some individuals who have the p.Pro250Arg pathogenic variant may have no signs of Muenke syndrome on physical or...GeneReviewsUniversity of Washington, 2021

Muenke syndrome is a condition characterized by the premature closure of the coronal suture of the skull (coronal craniosynostosis) during development. This affects the shape of the head and face. Other variable features include abnormalities of the hands or feet, hearing loss and developmental delay. Muenke syndrome is caused by...National Center for Advancing Translational Sciences
