Anomalies associated with cleft lip, cleft palate, or both

Area of Science:

• Medical Genetics
• Developmental Biology
• Pediatric Surgery

Background:

• Previous studies reported inconsistent frequencies (3-30%) of anomalies associated with cleft lip and palate.
• Recent findings suggested over half of children with clefts have associated malformations.

Purpose of the Study:

• To investigate the genetic and morphologic characteristics of patients with clefts.
• To determine the frequency of associated anomalies in a large cohort of patients with cleft lip, cleft palate, or both.

Main Methods:

• Review and examination of 1,000 patients diagnosed with cleft lip, cleft palate, or both.
• Analysis of the frequency and types of associated anomalies observed in the patient sample.

Main Results:

• Associated anomalies were identified in 63.4% of the 1,000-patient sample.
• Half of patients with multiple anomalies presented with recognized syndromes, sequences, or associations.
• The other half exhibited unique physical examination findings, suggesting one-of-a-kind syndromes.

Conclusions:

• The high prevalence of associated anomalies in clefting disorders has significant implications for genetic counseling.
• The findings necessitate a re-evaluation of the validity of previous genetic research conducted on populations with clefts.
• Understanding these associations is crucial for comprehensive patient care at craniofacial centers.
