Glycogen Storage Disease Type IX

Glycogen Storage Disease Type IX

Glycogen storage disease type VI (GSD VI) is a type of glycogen storage disease caused by a deficiency in liver glycogen phosphorylase or other components of the associated phosphorylase cascade system.

It is also known as "Hers' disease", after Henri G. Hers, who characterized it in 1959.

The scope of GSD VI now also includes glycogen storage disease type VIII, IX (caused by phosphorylase b kinase deficiency) and X (deficiency of protein kinase A). These were previously considered to be distinct GSD types.

The incidence of GSD VI is approximately 1 case per 65,000–85,000 births, representing approximately 30% all cases of glycogen storage disease. Approximately 75% of these GSD VI cases result from the X-linked recessive forms of phosphorylase kinase deficiency. All other forms are autosomal recessive.

Famous quotes containing the words storage, disease and/or type:

    Many of our houses, both public and private, with their almost innumerable apartments, their huge halls and their cellars for the storage of wines and other munitions of peace, appear to me extravagantly large for their inhabitants. They are so vast and magnificent that the latter seem to be only vermin which infest them.
    Henry David Thoreau (1817–1862)

    Your responsibility as a parent is not as great as you might imagine. You need not supply the world with the next conqueror of disease or a major movie star. If your child simply grows up to be someone who does not use the word “collectible” as a noun, you can consider yourself an unqualified success.
    Fran Lebowitz (20th century)

    Histories of the world omitted China; if a Chinaman invented compass or movable type or gunpowder we promptly “forgot it” and named their European inventors. In short, we regarded China as a sort of different and quite inconsequential planet.
    —W.E.B. (William Edward Burghardt)
