Abstract:
Gorlin syndrome is an autosomal dominant inherited condition that exhibits high penetrance and variable expressivity. The syndrome is caused by mutations in PTCH, a tumor suppressor gene that has been mapped to chromosome 9q22.3-q31. It is observed that most aggressive forms of keratocystic odontogenic tumor are the first signs of this syndrome which show a high recurrence rate due to its varied histopathological features. The other components are multiple basal cell carcinomas of the skin, intracranial calcifications and rib and vertebral anomalies. In addition, >100 minor criteria have been described with two major and one minor criteria or one major and three minor criteria necessary for confirmatory diagnosis. It is a rare syndrome having an estimated incidence of 1 in 50,000-150,000 in the general population with a 3:1 male/female gender predilection. Here, we report the case of a 14-year-old female patient diagnosed with Gorlin syndrome.
Insights
Gorlin syndrome, a rare genetic disorder caused by PTCH gene mutations, presents with diverse symptoms like keratocystic odontogenic tumors and basal cell carcinomas. This report details a case in a 14-year-old female patient.
Area of Science:
- Genetics
- Oncology
- Dermatology
Background:
- Gorlin syndrome is an autosomal dominant inherited disorder.
- It is caused by mutations in the PTCH tumor suppressor gene on chromosome 9q22.3-q31.
- Characterized by high penetrance and variable expressivity.
Observation:
- Aggressive keratocystic odontogenic tumors are often the initial clinical manifestation.
- These tumors exhibit a high recurrence rate due to diverse histopathological features.
- Other key features include basal cell carcinomas, intracranial calcifications, and skeletal anomalies.
Findings:
- Diagnosis requires specific criteria: two major and one minor, or one major and three minor criteria.
- The syndrome has an estimated incidence of 1 in 50,000-150,000.
- A notable male-to-female gender predilection of 3:1 is observed.
Implications:
- Understanding the genetic basis (PTCH mutations) is crucial for diagnosis and management.
- Early identification of keratocystic odontogenic tumors can aid in timely intervention.
- This case highlights the syndrome's presentation in a young female patient, contributing to clinical awareness.

The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
