Genetic Counselling

The dysplastic nevus syndrome is autosomal dominant. Approximately 50% of the offspring of an affected parent would be expected to have the gene for increased sensitivity to ultraviolet light. It is important to examine family members of patients who have had a melanoma for evidence of the dysplastic nevus syndrome. Approximately 40% of melanoma patients have a clearly very atypical nevus at the time of their presentation of the melanoma.
