In any country, people who inherit more of these low penetrance melanoma genes are more likely to get melanoma if they sun bathe.

The hypothesis then, is that inheritance of these putative low penetrance genes predisposes white skinned peoples to melanoma but that as this predisposition is weak, there may be only one or occasionally two cases in the family.

It is also possible that families carrying these low penetrance genes may have more cases of melanoma if they live in areas of the world where the environmental exposures are more extreme such as Queensland: that is, as a result of gene / environment interaction.

It must be noted however that a subset of PRA - affected Italian Greyhounds in the study carried only one copy of the IG - PRA1 risk allele, suggesting that the disease may represent a mode of inheritance called «Autosomal Dominant with Incomplete Penetrance» (ADIP).

In fact, many of the mutations that Embark screens are known to have incomplete penetrance, meaning even if a dog is «At Risk» for a condition doesn't mean that it's a done deal and the dog will develop the health condition.

This genetic mutation has a characteristic called «incomplete penetrance», which means that even if a dog has the mutation it may not penetrate and result in development of the disease.

Inheritance with incomplete penetrance means that other factors — other genes, gene regulators, and / or environment — are involved in the process that determines whether cataracts do or do not develop in any particular dog.

However, caution should be used in aggressively selecting against mutant alleles which have low penetrance or low risk for the disease state when the mutant alleles are common throughout the breed.

In contrast, an autosomal dominant mode of inheritance with a high degree of penetrance has been suggested for the pulverulent (dust - like) form of cataract observed in the Norwegian Buhund [116] and autosomal dominant with variable penetrance has been suggested for inherited posterior polar subcapsular cataracts in the Labrador and Golden retriever [117], although current anecdotal evidence indicates that in the Labrador cataracts could also be inherited as an autosomal recessive traiIn contrast, an autosomal dominant mode of inheritance with a high degree of penetrance has been suggested for the pulverulent (dust - like) form of cataract observed in the Norwegian Buhund [116] and autosomal dominant with variable penetrance has been suggested for inherited posterior polar subcapsular cataracts in the Labrador and Golden retriever [117], although current anecdotal evidence indicates that in the Labrador cataracts could also be inherited as an autosomal recessive traiin the Norwegian Buhund [116] and autosomal dominant with variable penetrance has been suggested for inherited posterior polar subcapsular cataracts in the Labrador and Golden retriever [117], although current anecdotal evidence indicates that in the Labrador cataracts could also be inherited as an autosomal recessive traiin the Labrador and Golden retriever [117], although current anecdotal evidence indicates that in the Labrador cataracts could also be inherited as an autosomal recessive traiin the Labrador cataracts could also be inherited as an autosomal recessive trait.
