Genetics of Glycogen-Storage Disease Type VII Clinical Presentation

History
The usual presenting symptom in Tarui disease (glycogen-storage disease type VII) is exertional fatigue. Most patients exhibit exertional fatigue in childhood and may experience nausea and vomiting, muscle cramps, hyperuricemia, myoglobinuria, or even frank anuria following high-intensity exercise. This constellation of signs and symptoms is characteristic not only of Tarui disease but a group of clinically and etiologically diverse conditions termed metabolic myopathies. The symptoms of exertional fatigue in patients with Tarui disease are typically more severe than those observed in McArdle disease (glycogen storage disease type V), the most common form of metabolic myopathy.
- Hemolysis due to partial erythrocyte phosphofructokinase (PFK) deficiency may cause jaundice.
- Hyperuricemia following exercise is due to accelerated degradation of muscle purine nucleotides, which serve as the substrates for the synthesis of uric acid. Manifestations of hyperuricemia may include arthritis.
- Blindness and psychomotor retardation may be the presenting symptoms of the infantile-onset type.
- Cardiac dysfunction, arrhythmia and anginal chest pain may be symptoms of the late-onset type.[11]
Physical
- Classic and late-onset
- Muscle weakness, most pronounced following exercise
- Fixed limb weakness
- Muscle contractures
- Jaundice
- Joint pain
- Fatal infantile variant
- Muscle weakness
- Cataracts
- Joint contractures
Causes
The cause of Tarui disease is genetic.
- Missense, splicing defects, and frameshift mutations in the gene encoding the M subunit of PFK have been discovered in patients with Tarui disease. The M subunit gene, mapped to band 12p13, contains 24 exons and is approximately 30 kilobase (kb) in length.
- Ashkenazi Jews share 2 common mutations in the gene. A splicing defect caused by the G-to-A base change at the first nucleotide in exon 5 accounts for 68% of mutant Ashkenazi alleles, and a deletion in exon 22 accounts for about 27% of mutant Ashkenazi alleles.[12]
