==Overview==  
 
Oculofaciocardiodental syndrome (OFCD) is a rare [[Congenital disorder|congenital condition]] affecting [[eyes]], [[heart]], [[face]] and [[teeth]]. This syndrome is a [[X-linked]] syndrome and it has been seen in [[heterozygous]] female only. Due to its lethal affects on male, there has been no report of affected male. Common [[signs]] and [[symptoms]] include [[cataract]], small deep-set eyes, long narrow face, [[heart defects]] and teeth with large roots.
Oculofaciocardiodental syndrome (OFCD) is a rare congenital condition affecting eyes, heart, face and teeth. This syndrome is a [[X-linked]] syndrome and it has been seen in [[heterygous]] female only. Due to its lethal affects on male, there has been no report of affected male. Common signs ad symptoms include [[cataract]], small deep-set eyes, long narrow face, heart defects and teeth with large roots.

===Diagnostic Study of Choice===
Diagnosis of oculofaciocardiodental syndrome is based on genetic analysis and its symptoms such as:
[[Diagnosis]] of oculofaciocardiodental syndrome is based on [[genetic analysis]] and [[clinical]] characteristics.
 
===History and Symptoms===
===Cardiac Abnormalities===
The majority of patients with [disease name] are asymptomatic.
 
OR
* [[Ventricular septal defect]]  
The hallmark of [disease name] is [finding]. A positive history of [finding 1] and [finding 2] is suggestive of [disease name]. The most common symptoms of [disease name] include [symptom 1], [symptom 2], and [symptom 3]. Common symptoms of [disease] include [symptom 1], [symptom 2], and [symptom 3]. Less common symptoms of [disease name] include [symptom 1], [symptom 2], and [symptom 3].
* [[Atrial septal defect]]  
===Physical Examination===
* [[Mild cardiomegaly]]  
* Physical examination of patients with Oculofaciocardiodental syndrome is usually remarkable for characteristic facial features, missing or abnormally small teeth, [[misaligned]] teeth, and defective tooth [[enamel]], and a heart murmur.
* [[Atrial hypertrophy]]
*[[Facial]] manifestations include a long, narrow face with distinctive facial features, including deep-set eyes and a broad nasal tip that is divided by a [[cleft]].
* [[Ventricular hypertrophy]]  
* [[Benign peripheral pulmonic stenosis]]
* [[Mitral valve prolapse]]
 
===Dental Abnormalities===
 
The specific dental findings (visible on a panoramic radiograph of the jaws) can be easily diagnosed by an orthodontist or a dentist.
 
* Radiculomegaly: The most consistent and pathognomic dental finding of oculofaciocardiodental syndrome is radiculomegaly (extremely long roots), particularly of the canines and occasionally of other teeth including [[premolar]]s and [[incisor]]s.
* Slow and delayed dental eruption: The dental eruption in both the deciduous and the permanent dentition is consistently slow and delayed.  
* Oligodontia
* Fused teeth
* [[Supernumerary teeth]]  
* Malformed permanent teeth
* [[Enamel|Enamel defects]]
* Root dilacerations
* Malposition
* [[Malocclusion]]

Overview

Oculofaciocardiodental syndrome (OFCD) is a rare congenital condition affecting eyes, heart, face and teeth. This syndrome is a X-linked syndrome and it has been seen in heterozygous female only. Due to its lethal affects on male, there has been no report of affected male. Common signs and symptoms include cataract, small deep-set eyes, long narrow face, heart defects and teeth with large roots.

Historical Perspective

Classification

  • There is no established system for classification of OFCD.

Pathophysiology

  • The genetic analysis in oculofaciocardiodental syndrome patients shows mutations in BCOR gene on chromosome Xp11.4 which has functions like maintaining tissue homeostasis and gene silencing by epigenetic mechanisms.[2]
  • BCOR gene provides instructions for making BCL6 corepressor protein. The BCL6 corepressor plays an essential role in early embryonic development, including the formation of the eyes and several other tissues and organs like the cardiovascular system and face tissues.
  • It can also involve in specifying the left and right sides of the body in the developing embryo.

Causes

Differentiating OFCD from other diseases

Epidemiology and Demographics

  • Oculofaciocardiodental syndrome is very rare; the incidence is estimated to be less than per million people.[4]
  • It is primarily only found in females while it is highly rare in males.

Risk Factors

There are no established risk factors for OFCD syndrome.

Screening

There is insufficient evidence to recommend routine screening for OFCD syndrome.

Natural History, Complications, and Prognosis

Diagnosis

Diagnostic Study of Choice

Diagnosis of oculofaciocardiodental syndrome is based on genetic analysis and clinical characteristics.

History and Symptoms

The majority of patients with [disease name] are asymptomatic. OR The hallmark of [disease name] is [finding]. A positive history of [finding 1] and [finding 2] is suggestive of [disease name]. The most common symptoms of [disease name] include [symptom 1], [symptom 2], and [symptom 3]. Common symptoms of [disease] include [symptom 1], [symptom 2], and [symptom 3]. Less common symptoms of [disease name] include [symptom 1], [symptom 2], and [symptom 3].

Physical Examination

  • Physical examination of patients with Oculofaciocardiodental syndrome is usually remarkable for characteristic facial features, missing or abnormally small teeth, misaligned teeth, and defective tooth enamel, and a heart murmur.
  • Facial manifestations include a long, narrow face with distinctive facial features, including deep-set eyes and a broad nasal tip that is divided by a cleft.

Facial Abnormalities

facial abnormalities[8]

Ocular Abnormalities

Laboratory findings

  • There are no diagnostic laboratory findings associated with OFCD

Electrocardiogram

  • In patients with OFCD, ECG is usually normal.

X-ray

Dental Abnormalities

The specific dental findings (visible on a panoramic radiograph of the jaws) can be easily diagnosed by an orthodontist or a dentist.[1]

  • Radiculomegaly: The most consistent and pathognomic dental finding of oculofaciocardiodental syndrome is radiculomegaly (extremely long roots), particularly of the canines and occasionally of other teeth including premolars and incisors.
  • Slow and delayed dental eruption: The dental eruption in both the deciduous and the permanent dentition is consistently slow and delayed.
  • Oligodontia
  • Fused teeth
  • Supernumerary teeth
  • Malformed permanent teeth
  • Enamel defects
  • Root dilacerations
  • Malposition
  • Malocclusion
dental abnormalities[1]
dental abnormalities[1]
  • Intraoral radiographs in most pf the patients show abnormal dental root maturation with pulp stone-like calcification (PSLC) in teeth pulp and calcified dental papilla (CDP) beneath dental roots.[8]
  • Cephalometric radiograph in some patients reveals elongated lower facial height and steep mandibular plane angle.[1]. Also abdominal X-ray may show cardiomegaly or pulmonary oedema andplueral effusion in severe cases.

Echocardiography

  • Echocardiography may be helpful in detection and following up of cardiovascular manifestation of OFCD.
  • Echocardiographic findings of OFCD include:

CT scan

MRI

Other Imaging Findings

  • There are no other imaging findings associated with OFCD syndrome

Other Diagnostic Studies

There are no other diagnostic studies associated with OFCD syndrome

Treatment

  • The OFCD management includes surgical interventions.

Surgery

  • Surgery is the mainstay of treatment for OFCD which includes orthodontic treatment for dental manifestation and orthognathic surgery to solve skeletal anomalies, and cataract surgery.
  • Orthodontic and orthognathic surgery include:[3]
    • Lower fixed appliance
    • Upper fixed appliance
    • Maxillary impaction
    • Bilateral sagittal split osteotomy
    • Genioplasty
