In general terms, glycogen storage diseases are divided in 2 groups, those with liver involvement and those with neuromuscular involvement and weakness. McArdle disease (glycogen storage disease type V) belongs to the second group.

In these late-onset diseases, the causes of onset, progression and association are poorly known due to the complexity of the genetic mechanisms involved as well as the interaction between these mechanisms and the environment. While some mutations that contribute to these diseases are present at birth, others may appear as failures of genome replication mechanisms. Some of these failures could be attributed to mutagens in the environment. In addition to causing mutations, mutagens can also trigger the expression of otherwise dormant genes. Despite being inevitable, the onset of disease may be regulated by modifier genes. Thus, this combination of accumulated mutations and inappropriately activated genes may express in the progressive association of the 3 diseases in this patient. In McArdle's disease, there is a glycogen phosphorylase deficiency in skeletal muscle. In RPE there are isoforms of glycogen phosphorylase in muscle, so the mutation of the PYGM gene would have the potential to produce RPE dysfunction.<a class="elsevierStyleCrossRef" href="#bib0050"><span class="elsevierStyleSup">10</span></a> A further possibility is that a mutation in the PYGM gene could successively cause an imbalance in not necessarily nearby locus involved in RPE and lung function. Gene expression is controlled by regulatory elements that can be located far along the chromosome (short and long arm of chromosome 11) and even in other chromosomes (chromosome 6) and give rise to chromosomal interactions that may involve physical contacts between different chromosomes.</p><p id="par0040" class="elsevierStylePara elsevierViewall">There are no reported cases of IPF associated with McArdle's disease, retinal dystrophies or both.
