Auriculo-condylar syndrome.

Area of Science:

• Genetics
• Developmental Biology
• Medical Science

Background:

• Auriculo-condylar syndrome (ACS) arises from developmental errors in the first and second pharyngeal arches.
• It follows an autosomal dominant inheritance pattern, observed in both familial and sporadic cases.
• ACS exhibits significant phenotypic variability and variable expressivity.

Observation:

• This report details a female patient diagnosed with auriculo-condylar syndrome.
• The study includes the patient's family pedigree, documenting the genetic transmission.
• Clinical findings, diagnostic procedures, and treatment strategies are presented.

Findings:

• The patient presented with characteristic signs of ACS, including auricular malformations and mandibular hypoplasia.
• Analysis of the family pedigree confirmed the autosomal dominant inheritance pattern.
• The case illustrates the wide spectrum of clinical manifestations in ACS.

Implications:

• Understanding the variable expressivity of ACS is crucial for accurate diagnosis and genetic counseling.
• This case contributes to the literature on auriculo-condylar syndrome, aiding future research.
• Effective management strategies for ACS require a comprehensive approach considering its diverse clinical features.
