Summary
Understanding melanoma susceptibility is key for targeted prevention. This review covers common low-risk genes, like those for red hair, and rare high-risk genes.
Area of Science:
- Genetics
- Oncology
- Dermatology
Background:
- Melanoma incidence is rising globally.
- Identifying individuals at higher risk is essential for effective prevention strategies.
Purpose of the Study:
- To review current knowledge on genetic factors influencing melanoma susceptibility.
- To differentiate between common low-risk and rare high-risk genetic determinants.
Main Methods:
- Literature review of genetic association studies.
- Synthesis of findings on genes related to pigmentation and DNA repair.
- Analysis of gene frequencies and penetrance.
Main Results:
- Common genetic variants, such as those affecting the MC1R gene (associated with red hair), contribute to lower-risk susceptibility.
- Rare high-risk mutations in genes like CDKN2A significantly increase melanoma risk.
- Multiple genetic factors interact to modulate an individual's overall susceptibility.
Conclusions:
- Genetic predisposition plays a significant role in melanoma development.
- A comprehensive understanding of both common and rare genetic variants is crucial for personalized melanoma risk assessment and prevention.
- Further research is needed to elucidate the complex interplay of genetic factors in melanoma.

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

02:21Cancers Originate from Somatic Mutations in a Single Cell
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

01:19Pigmentation
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

02:59Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:20The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
