Myth --McArdle’s Disease is inherited in an autosomal recessive pattern.

Fact -- It is possible for rare cases of McArdle’s to be inherited in an autosomal dominant pattern. Autosomal RECESSIVE means that BOTH parents must pass on the defective gene. Even if neither parent actually has the disease each child will have a 25% chance of being affected. With autosomal DOMINANT inheritance, only one parent need pass on the gene yet each child has a 50% chance of being born with the disease. Medical historians have recorded people who have both a parent & child - and even 3rd generation -diagnosed with McArdle’s. These cases are not yet documented in the medical literature but appear to have no other explanation except dominant inheritance.
