New multiple congenital anomalies/mental retardation syndrome with cardio-facio-cutaneous involvement--the CFC
Insights
Cardio-Facio-Cutaneous (CFC) syndrome is a rare genetic disorder characterized by heart defects, distinct facial features, and ectodermal abnormalities. The exact cause of CFC syndrome remains unknown, despite its genetic presumption.
Area of Science:
- Genetics
- Pediatrics
- Dermatology
Background:
- A previously undefined multiple congenital anomalies/mental retardation syndrome was identified.
- This syndrome was designated Cardio-Facio-Cutaneous (CFC) syndrome.
Observation:
- Eight patients presented with a consistent set of anomalies.
- Key features included congenital heart defects (pulmonic stenosis, atrial septal defect), characteristic facial appearance, ectodermal abnormalities (sparse, friable hair; skin changes like ichthyosis), and growth failure.
- Facial features included a high forehead, supraorbital hypoplasia, antimongoloid palpebral slant, depressed nasal bridge, and posteriorly angulated ears.
Findings:
- All observed cases were sporadic with no family history or consanguinity.
- Chromosomal analyses were normal in affected individuals.
- The underlying genetic cause of CFC syndrome is currently unknown.
Implications:
- This description establishes CFC syndrome as a distinct clinical entity.
- Further research is needed to elucidate the genetic etiology of CFC syndrome.
- Understanding the genetic basis will aid in diagnosis, genetic counseling, and potential therapeutic strategies.
Abstract:
Eight patients (4 males, 4 females) were affected with a previously undefined multiple congenital anomalies/mental retardation syndrome which was designated the Cardio-Facio-Cutaneous (CFC) syndrome and which includes congenital heart defects, characteristic facial appearance, ectodermal abnormalities, and growth failure. Cardiac defects were variable, the most common being pulmonic stenosis and atrial septal defect. Typical facial characteristics were high forehead with bitemporal constriction, hypoplasia of supraorbital ridges, antimongoloid slant of palpebral fissures, depressed bridge of nose, and posteriorly angulated ears with prominent helices. The hair was usually sparse and friable. Skin changes varied from patchy hyperkeratosis to a severe generalized ichthyosis-like condition. All cases were sporadic in occurrence, there was no family history of consanguinity, and chromosomes were normal. Although presumed to be genetic, the cause of the CFC syndrome remains unknown.
