A glycogen storage disease(GSD, also glycogenosisand dextrinosis) is a metabolic disordercaused by a deficiency of an enzymeor transport proteinaffecting glycogen synthesis, glycogen breakdown, or glucose breakdown, typically in musclesand/or livercells. [1] GSD has two classes of cause: genetic and environmental.
Glycogen storage disease type I (GSD I) is an inherited disease that prevents the liver from properly breaking down stored glycogen, which is necessary to maintain adequate blood sugar levels. GSD I is divided into two main types, GSD Ia and GSD Ib, which differ in cause, presentation, and treatment. There are also possibly rarer subtypes, the ...
Glycogen storage disease type V (GSD5, GSD-V), [ 1 ] also known as McArdle's disease, [ 2 ] is a metabolic disorder, one of the metabolic myopathies, more specifically a muscle glycogen storage disease, caused by a deficiency of myophosphorylase. [ 3 ][ 4 ] Its incidence is reported as one in 100,000, roughly the same as glycogen storage ...
gsd iii is ar In regards to genetics glycogen storage disease type III is inherited in an autosomal recessive pattern (which means both parents need be a carrier), and occurs in about 1 of every 100,000 live births.
The severity of this disease varies on the amount of enzyme produced. GSD IV is autosomal recessive, which means each parent has a mutant copy of the gene, but show no symptoms of the disease. Having an autosomal recessive inheritance pattern, males and females are equally likely to be affected by Andersen's disease.
If there are warning signs of prostate cancer, they can include: Blood in the urine or semen. Problems urinating—including feeling like you need to urinate more often or a slow or weak stream ...
Late-onset hypogonadism. Late-onset hypogonadism (LOH) or testosterone deficiency syndrome (TDS) [ 1 ][ 2 ] is a term for a condition in older men characterized by measurably low testosterone levels and clinical symptoms mostly of a sexual nature, including decreased desire for mating, fewer spontaneous erections, and erectile dysfunction. [ 3 ]
GSD-II is broadly divided into two onset forms based on the age symptoms occur. [5] Infantile-onset form is usually diagnosed at 4–8 months; muscles appear normal but are limp and weak preventing the child from lifting their head or rolling over. As the disease progresses, heart muscles thicken and progressively fail.
