Zechi-Ceide Syndrome
Zechi-Ceide Syndrome: Overview
Definition
A rare genetic developmental disorder characterized by distinctive craniofacial features, digital abnormalities, and developmental delay. First described by Zechi-Ceide and colleagues.
Key Characteristics
- Facial dysmorphisms with distinctive features
- Limb and digital anomalies
- Growth abnormalities
- Developmental delays
- Rare autosomal recessive inheritance pattern
Epidemiology
- Extremely rare condition with fewer than 20 reported cases worldwide
- No gender predilection
- Higher prevalence in consanguineous families
- Usually diagnosed in early infancy or childhood
Clinical Manifestations
Craniofacial Features
- Facial Characteristics
- Broad forehead with prominent metopic ridge
- Hypertelorism with downslanting palpebral fissures
- Broad nasal bridge with bulbous nasal tip
- Long philtrum with thin upper lip
- Micrognathia in early life
- Dental Anomalies
- Delayed tooth eruption
- Dental crowding
- Malocclusion
Skeletal Manifestations
- Digital Abnormalities
- Brachydactyly (shortened digits)
- Clinodactyly of fifth fingers
- Broad thumbs and halluces
- Syndactyly in some cases
- Other Skeletal Features
- Short stature
- Delayed bone age
- Vertebral anomalies
- Joint hypermobility
Neurological Features
- Central Nervous System
- Variable cognitive impairment
- Speech delay
- Motor developmental delay
- Behavioral abnormalities
Genetic Basis and Inheritance
Molecular Genetics
- Genetic Mutations
- Associated with specific gene mutations (exact gene still under research)
- Complex genetic interactions
- Role of developmental pathway genes
- Inheritance Pattern
- Autosomal recessive transmission
- High carrier frequency in certain populations
- Increased risk in consanguineous marriages
Genetic Counseling
- Family Planning
- 25% recurrence risk in siblings
- Importance of carrier testing
- Prenatal diagnosis options
- Screening Recommendations
- Family history assessment
- Genetic testing protocols
- Risk assessment
Diagnostic Approach
Clinical Evaluation
- Physical Examination
- Detailed facial examination
- Assessment of growth parameters
- Skeletal survey
- Neurological evaluation

- Speech and language development
- Social skills
Laboratory and Imaging Studies
- Genetic Testing
- Molecular genetic analysis
- Chromosomal microarray
- Whole exome sequencing when indicated
- Imaging Studies
