Summaries for Glycogen Storage Disease Ixc

Disease Ontology : 12 A glycogen storage disease IX characterized by autosomal recessive inheritance of hepatomegaly, hypotonia, growth retardation, and liver dysfunction with onset in childhood and improvement of symptoms with age that has material basis in homozygous and compound heterozygous mutation in the PHKG2 gene on chromosome 16p11.

MalaCards based summary : Glycogen Storage Disease Ixc, also known as gsd9c, is related to alagille syndrome 1 and glycogen storage disease due to liver phosphorylase kinase deficiency. An important gene associated with Glycogen Storage Disease Ixc is PHKG2 (Phosphorylase Kinase Catalytic Subunit Gamma 2). Affiliated tissues include liver, skeletal muscle and bone, and related phenotypes are muscular hypotonia and splenomegaly

OMIM : 58 Glycogen storage disease IXc is characterized by onset in childhood of hepatomegaly, hypotonia, growth retardation in childhood, and liver dysfunction. These symptoms improve with age in most cases; however, some patients may develop hepatic fibrosis or cirrhosis (Burwinkel et al., 1998). (613027)

UniProtKB/Swiss-Prot : 76 Glycogen storage disease 9C: A metabolic disorder manifesting in infancy with hepatomegaly, growth retardation, hypotonia, liver dysfunction, and elevated plasma aminotransferases and lipids. These symptoms improve with age in most cases; however, some patients may develop hepatic fibrosis or cirrhosis.
