AI Article Synopsis

  • The study aimed to compare the cephalometric measurements of patients with velocardiofacial syndrome to those without the syndrome.
  • The research involved analyzing lateral cephalograms of 18 patients with the syndrome and 18 age- and gender-matched controls, all before any orthodontic treatment.
  • Results showed significant morphological differences in skull base length, nasal bone position, maxilla height, jaw angles, and other measurements, highlighting the need for tailored treatment protocols for these patients, while also questioning previous claims about pharyngeal dimension differences.

Article Abstract

Objective: To compare cephalometric measurements of patients with and without velocardiofacial syndrome.

Design: Cross-sectional.

Setting: Public tertiary craniofacial center.

Subjects: Lateral cephalograms of 18 patients with velocardiofacial syndrome and 18 controls without morphofunctional alterations, matched for gender and age; all cephalograms were obtained before orthodontic intervention.

Main Outcome Measures: The cephalograms were manually traced and digitized for the achievement of linear and angular measurements.

Results: Individuals with velocardiofacial syndrome presented a reduced length of the skull base, retrusion of nasal bones, reduced posterior height of the maxilla, increased gonial angle, increased interincisal angle, greater lingual inclination of the mandibular incisors, reduced nasolabial angle, and reduced nasal depth compared with the control group.

Conclusions: Patients with velocardiofacial syndrome presented morphological differences compared with individuals without morphofunctional alterations, which might be considered in the evaluation of patients with suspected diagnosis of the syndrome, as well as for the establishment of treatment protocols adequate to their needs. The present findings did not support the hypothesis of differences in pharyngeal dimensions mentioned by other authors, suggesting that the velopharyngeal insufficiency in these patients may be caused by functional alterations rather than by anatomical differences.

Background: 22q11 deletion syndrome consists of a variable grouping of phenotypic features and immunological defects secondary to the loss of genetic material located in the 22q11.2 band. The 22q11 deletion spectrum encompasses different syndromes related to the same etiology and with overlapping anomalies, including DiGeorge syndrome, velocardiofacial syndrome, among others.

Velocardiofacial syndrome (VCFS), also known as 22q11.2 deletion syndrome or DiGeorge syndrome, is a complex genetic disorder associated with a spectrum of phenotypic features, including craniofacial anomalies, congenital heart defects, and neurodevelopmental challenges. Among the more concerning, though under-recognized, presentation in VCFS is carotid artery medialization-a finding that places patients at substantial risk for vascular injury during pharyngeal surgeries.

Objective: One in every 4 individuals born with a 22q11.2 microdeletion will develop schizophrenia. Thirty years of clinical genetic testing capability have enabled detection of this major molecular susceptibility for psychotic illness.

Article Synopsis
  • - The 2q31 deletion is linked to a specific set of features including developmental delays, short stature, distinct facial traits (like microcephaly and ear deformities), and limb defects, identified in 38 patients so far.
  • - An 8-year-old girl with symptoms resembling velocardiofacial syndrome was diagnosed with a 2q31 microdeletion, confirmed through genetic testing that showed a non-continuous deletion between certain cytobands, along with treatment for her speech and swallowing difficulties.
  • - This case is the first recorded instance of a complex deletion in the 2q31 regions, enhancing knowledge about the conditions linked to these genetic changes, and highlights the importance of advanced diagnostic methods to distinguish it

Background: Early detection of rare genetic diseases, including velocardiofacial syndrome (VCFS), is essential for patient well-being. However, their rarity and limited clinical experience of physicians make diagnosis challenging. Deep learning algorithms have emerged as promising tools for efficient and accurate diagnosis.
