Saethre-Chotzen syndrome Overview Saethre-Chotzen syndrome (SCS) is a rare genetic disorder characterized by craniosynostosis (premature fusion of skull bones), leading to an asymmetrical head/face, low hairline, droopy eyelids (ptosis), and often, partial webbing of fingers. It is inherited in an autosomal dominant manner, typically caused by TWIST1 gene mutations. Treatment usually involves surgeries to release skull sutures and manage facial, limb, or developmental issues. Symptoms Craniosynostosis: Premature closure of skull bones (usually the coronal suture) leading to an abnormally shaped head. Facial Asymmetry: One side of the face may look different from the other. Droopy Eyelids (Ptosis): A common feature. High Forehead/Low Hairline: A flat forehead and low hairline are common. Ear Anomalies: Small, low-set, or malformed ears. Midface Hypoplasia: The mid-facial region may appear flat or underdeveloped. Beaked Nose: A distinct nose shape. Causes TWIST1 Gene Mutation:...
Zimmerman-Laband syndrome Overview Laband syndrome, also known as Zimmerman-Laband syndrome, is an extremely rare genetic disorder characterized by abnormalities of the head and facial (craniofacial) area and the hands and feet. Most children with this disorder have abnormally large gums (gingival fibromatosis). Overgrown gums may affect the ability to chew, swallow, and/or speak. In addition, affected infants may exhibit abnormally long, thin fingers and toes and/or deformed (dysplastic) or absent nails at birth. In some cases, mental retardation may also be present. In most cases, Laband syndrome is believed to be inherited as an autosomal dominant trait. However, evidence of autosomal recessive inheritance has also been reported. Symptoms Laband syndrome is an extremely rare genetic disorder characterized by abnormalities of the head and face (craniofacial) area and the fingers and toes, particularly the thumbs and great toes. Abnormalities affecting the fingers and toes may be appa...
