Baraitser-Winter cerebrofrontofacial syndrome.

Area of Science:

• Genetics
• Developmental Biology
• Clinical Medicine

Background:

• Baraitser-Winter cerebrofrontofacial syndrome (BWCFF) is a rare, multi-system developmental disorder.
• Key features include intellectual disability, distinctive facial anomalies (metopic ridging, ptosis, hypertelorism), cortical malformations, and ocular colobomata.

Purpose of the Study:

• To provide a comprehensive overview of BWCFF.
• To present novel findings from four recently diagnosed patients.
• To discuss diagnosis, management, mutation spectrum, and genetic counseling.

Main Methods:

• Clinical characterization of patients.
• Review of existing literature on BWCFF.
• Analysis of mutation spectrum in ACTB and ACTG1 genes.

Main Results:

• BWCFF is associated with intellectual disability, characteristic facial features, and potential organ system involvement.
• Missense mutations in ACTB and ACTG1 are identified as the cause of BWCFF.
• Novel clinical findings in four patients are presented.

Conclusions:

• BWCFF is a genetically determined syndrome with a defined set of clinical manifestations.
• Accurate diagnosis and management are crucial for affected individuals.
• Understanding the mutation spectrum aids in genetic counseling and future research.
