Definition and Overview
The Scalp-Ear-Nipple Syndrome, also known as SEN syndrome or Finlay-Marks syndrome, is a rare genetic condition characterized by aplasia cutis congenita of the scalp, breast anomalies, and external ear abnormalities. This autosomal dominant disorder was first described in 1978 and affects various body parts beyond the triad symptoms. Genetic mutations in the KCTD1 gene are associated with the syndrome, leading to a range of physical abnormalities. Diagnosis involves physical examinations and genetic testing to confirm the condition.
Clinical Features of Scalp-Ear-Nipple Syndrome
Scalp-Ear-Nipple Syndrome presents with aplasia cutis congenita of the scalp, breast anomalies, and external ear abnormalities. The syndrome is characterized by distinct physical abnormalities affecting these areas.
Aplasia Cutis Congenita of the Scalp
Aplasia Cutis Congenita of the Scalp is a key feature of Scalp-Ear-Nipple Syndrome characterized by areas of hairless raw skin present at birth. This condition is one of the distinctive clinical hallmarks of the syndrome.
Breast Anomalies
The Scalp-Ear-Nipple Syndrome is associated with breast anomalies that can range from hypothelia or athelia to amastia. This condition presents a spectrum of variations in breast development, contributing to the distinct clinical features of the syndrome.
External Ear Abnormalities
Scalp-Ear-Nipple Syndrome manifests with external ear abnormalities, including hypoplastic ears with almost absence of pinnae. These features contribute to the unique clinical profile of the syndrome, often presenting alongside other characteristic physical abnormalities.
Pathogenic missense variants in the KCTD1 gene are linked to the autosomal dominant Scalp-Ear-Nipple Syndrome, resulting in aplasia cutis congenita of the scalp, hairless posterior scalp nodules, absent or rudimentary nipples, breast aplasia, and external ear anomalies.
Involvement of KCTD1 Gene
Pathogenic missense variants in the potassium channel tetramerization domain-containing 1 (KCTD1) gene are associated with autosomal dominant Scalp-Ear-Nipple Syndrome (SENS). These mutations lead to aplasia cutis congenita of the scalp, hairless posterior scalp nodules, absent or rudimentary nipples, breast aplasia, and external ear anomalies, contributing to the distinct clinical features of the syndrome.
Diagnosis and Evaluation
Diagnosis of Scalp-Ear-Nipple Syndrome typically involves a thorough physical examination and genetic testing to confirm the presence of the condition; Physicians may assess the characteristic features, including scalp abnormalities, breast anomalies, and ear malformations to establish a diagnosis accurately.
Physical Examination
During the physical examination for Scalp-Ear-Nipple Syndrome, healthcare providers assess the scalp for aplasia cutis congenita, evaluate breast structure for anomalies, and examine the ears for abnormalities. These clinical assessments are crucial in identifying the characteristic features of the syndrome and guiding further diagnostic steps.
Genetic Testing
Genetic testing plays a crucial role in confirming the diagnosis of Scalp-Ear-Nipple Syndrome by identifying pathogenic missense variants in the KCTD1 gene. This process helps determine the presence of specific mutations associated with the syndrome٫ aiding in accurate diagnosis and genetic counseling.
