Abstract:
Five unrelated patients (a male and 4 females) were affected with a previously undefined multiple congenital anomalies/mental retardation syndrome which has been designated the facio-cutaneous-skeletal (FCS) syndrome and which includes mental retardation with specific sociable, humorous behavior, characteristic facial appearance, excessive generalized skin, postnatal growth failure, and skeletal involvement. Consanguinity was noted in 2 patients, thus autosomal recessive inheritance is suggested.
Insights
A new syndrome, facio-cutaneous-skeletal (FCS) syndrome, is defined, affecting five patients with multiple congenital anomalies and mental retardation. Autosomal recessive inheritance is suggested due to consanguinity in two families.
Area of Science:
- Medical Genetics
- Clinical Dysmorphology
- Pediatric Neurology
Background:
- Multiple congenital anomalies and intellectual disability syndromes represent a significant diagnostic challenge.
- Early identification and characterization of novel genetic syndromes are crucial for accurate diagnosis and management.
Observation:
- Five unrelated patients (1 male, 4 females) presented with a distinct constellation of features.
- Key features included mental retardation with unique sociable behavior, characteristic facial appearance, generalized skin excess, postnatal growth failure, and skeletal abnormalities.
Findings:
- The observed phenotype defines a previously unrecognized multiple congenital anomalies/mental retardation syndrome, designated facio-cutaneous-skeletal (FCS) syndrome.
- The presence of consanguinity in two families suggests a potential autosomal recessive inheritance pattern for FCS syndrome.
Implications:
- Recognition of FCS syndrome aids in diagnosing patients with overlapping features, improving genetic counseling.
- Further research into the genetic basis of FCS syndrome is warranted to understand its etiology and develop targeted therapies.
