Genetic Aspects of Congenital Anomalies of the External Ear in Children: A Comparative Analysis with Healthy Children

Abstract

Congenital anomalies of the external ear, although relatively rare, represent an important subset of craniofacial malformations with significant implications for auditory function and psychosocial development. These anomalies can range from minor structural deviations to severe malformations such as microtia or anotia, often associated with syndromic or nonsyndromic genetic conditions. This study aims to explore the genetic underpinnings of congenital external ear anomalies, focusing on the role of inherited and de novo mutations in specific genes and the influence of environmental factors during gestation. Utilizing advanced genetic testing methods, including whole-genome sequencing and comparative genomic hybridization, we compare genetic data from children with external ear anomalies to healthy counterparts. Our findings provide insights into the genetic predispositions contributing to these conditions and highlight the potential for early diagnostic and therapeutic interventions. The study underscores the importance of integrating genetic counseling and precision medicine in managing congenital anomalies of the external ear.
