About 1 in 10 cases are inherited from the mother or the father. When the condition is inherited, other family members could also be affected. A person who has this chromosome deletion has a 1 in 2 chance of passing the problem to a child. So both parents can have their blood studied to look for the deletion Velo-Cardio-Facial syndrome (VCFS) is a genetic, autosomal dominant condition defined by Shprintzen in 1978. Its frequency is estimated at 1 per 4000 live births. In most patients, a deletion (Figure 2) on chromosome 22q11.2 (Figure 1a and 1b) is responsible for the syndrome However, it is estimated that velocardiofacial syndrome is inherited this way in only 10 percent to 15 percent of cases. Most of the time neither of the parents has the syndrome nor carries the defective gene, and the cause of the deletion is called sporadic
Velocardiofacial syndrome is one of the most common multiple-anomaly syndromes in humans. With its many otolaryngologic manifestations and its almost ubiquitous effects on speech, language, hearing, immune dysfunction, and airway problems, velocardiofacial syndrome may be the most common genetic disorder seen by pediatric otolaryngologists Purpose of review: Velo-cardio-facial syndrome has emerged from obscurity to become one of the most researched disorders this past decade. It is one of the most common genetic syndromes in humans, the most common contiguous gene syndrome in humans, the most common syndrome of cleft palate, and the most common syndrome of conotruncal heart malformations Velocardiofacial syndrome Velocardiofacial syndrome (VCFS) is an autosomal dominant condition caused by a 3-Mb deletion of contiguous genes on chromosome 22q11.2. Multiple organ systems are affected, including the face, palate, and heart Velocardiofacial syndrome is a condition that is either inherited or occurs spontaneously as an autosomal dominant genetic mutation. Specifically, in children with VCFS, a segment of the long arm of chromosome 22 is absent. VCFS does not occur because of anything the mother did or did not do during pregnancy
22q11.2 deletion syndrome is a disorder that involves many different areas of the body and can vary greatly in severity among people with the condition. Signs and symptoms may include: cleft palate, heart defects, recurrent infections, unique facial characteristics, feeding problems, kidney abnormalities, hypoparathyroidism, thrombocytopenia, scoliosis, hearing loss, developmental delay, and. Velocardiofacial syndrome (VCFS; from the Latin velum - palate, cardia - heart, and facies - to do with the face) is a genetic disorder involving chromosome 22 (a deletion at 22q11). Its features include c ardiac defects, a bnormal facies, t hymic hypoplasia, c left palate and h ypocalcaemia - hence it is termed 'CATCH 22') VCFS is inherited in an autosomal dominant fashion, meaning if one parent has the syndrome, each child has a 50 percent chance of inheriting it. Most children born with VCFS have a small part of chromosome 22 missing. The exact location of this deleted segment is 22q11.2, which is why VCFS is also known as 22q11.2 deletion syndrome
Velocardiofacial syndrome (VCFS) is the most common known microdeletion in humans. It is also the most common known genetic risk factor for schizophrenia. The aim of this article is to describe the clinical characteristics of the syndrome, with emphasis on the myriad psychiatric disorders and abnormal behaviors from a developmental perspective Most patients with velocardial facial syndrome arise from a de novo microdeletion, with subsequent autosomal dominant inheritance. Prevalence ranges from 1 to 2 per 4,000 live births, with an increased incidence in patients with cardiovascular malformations. There is no male or female predominance VELO-CARDIO-FACIAL syndrome (VCFS), also known as DiGeorge or Shprintzen syndrome, is associated with small interstitial deletions of chromosome 22q11 in 80% to 85% of individuals. 1 It was first described by Shprintzen et al 2 and has an estimated prevalence of 1 in 4000 births. 3 The syndrome is characterized by distinctive dysmorphology, congenital heart disease, and learning disabilities.
Genetics DiGeorge syndrome is inherited in an autosomal dominant pattern. DiGeorge syndrome is caused by a heterozygous deletion of part of the long arm (q) of chromosome 22, region 1, band 1, sub-band 2 (22q11.2). Approximately 80-90% of patients have a deletion of 3 Mb and 8% have a deletion of 1.5Mb Velocardiofacial syndrome is a genetic disorder that appears at birth and causes many health problems, ranging from palate openings to heart defects. The severity of symptoms varies from child to child. You may also hear this syndrome called 22q11.2 deletion syndrome, DiGeorge syndrome, Shprintzen syndrome, or conotruncal anomaly face syndrome
Each fetus acquires two copies of chromosome 22, which are inherited from each parent. Velocardiofacial syndrome arises when a portion of chromosome 22 is deleted. This equates to a missing 30 to 40 genes normally available to a person Velo-Cardio-Facial Syndrome (VCFS) is a genetic disorder caused by the deletion of part of chromosome 22. It occurs in approximately one in 4000 births and there are now more than 100 physical phenotypic features reported. VCFS affects every major system in the body and this 2005 book was the first to describe its full clinical impact What causes velo-cardio facial syndrome? While the exact cause is unknown, many children with VCFS have a missing portion of chromosome 22. In some families (10-15%) the condition may be inherited; mostly however is occurs as a sporadic mutation without coming from either parent. What are the signs/symptoms of velo-cardio facial syndrome Velocardiofacial syndrome, or VCFS, is a complex syndrome that has been associated with more than 30 different characteristics, including defects of the palate, heart defects, learning disabilities and distinct facial features. The severity of VCFS and the characteristics that appear vary widely between individuals A promising approach to investigating genetic aspects of the disorder is to evaluate a group of patients with a defined genetic disorder. Individuals diagnosed with velocardiofacial syndrome (VCFS, also called 22q11.2 Deletion Syndrome) fit this description in that they have a high rate of psychiatric disorders, with up to 30% incidence of.
Introduction. DiGeorge and Velo-Cardio-facial syndromes are genetic conditions with overlapping features, including congenital heart defect (CHD), facial anomalies, hypoplastic thymus with immune deficit, palatal anomalies, neonatal hypocalcemia, speech and learning disabilities. 1,3 Cytogenetic and molecular studies have demonstrated that microdeletion of chromosome 22q11.2 (del22) is. DiGeorge/Velocardiofacial Syndrome (22q and 10p) FISH Panel and DiGeorge/Velocardiofacial Syndrome Type II (10p) FISH are also available. FISH analysis is indicated on the parents of an affected child since approximately 6% of affected probands will have inherited the deletion from a parent. Technical Information; Methodology

The DiGeorge/velocardiofacial syndrome (DGS/VCFS) (OMIM 188400/OMIM 192430) is the most common deletion syndrome in humans, with an incidence of 1:4000 newborns 34. The genetic cause is gene. Velocardiofacial (VCF) syndrome refers to areas of the body that can be affected. Velo refers to the palate (roof of the mouth). Babies with VCF are at an increased risk of being born with a cleft palate. The palate may also have poor muscle movement. Both these features put a child at risk for speech problems Velo-cardio-facial syndrome (VCFS) is a common genetic disorder among individuals with cleft plate and is associated with hemizygous deletions in human chromosome 22q11. Toward the molecular definition of the deletions, we constructed a physical map of 22q11 in the form of overlapping YACs Thirty-nine patients with the velo-cardio-facial syndrome are described in order to further delineate this probably common recurrent pattern congenital malformation syndrome. Frequent features include cleft palate, cardiac anomalies, typical facies, and learning disabilities. Less frequent findings include microcephaly, mental retardation.
