Genetic counseling Transmission is autosomal recessive. Offspring of a proband. Of the 40 pathogenic variants identified, 29 are within the catalytic domain of goucogenosis enzyme.

Successive liver biopsies showed hepatocellular periodic-acid Schiff-positive diastase-resistant inclusions and hepatic fibrosis that was nonprogressive over 3 years. Support Center Support Center. TEXT A number sign is used with this entry because glycogen storage disease type IV GSD4 is caused by homozygous or compound heterozygous mutation in the GBE1 genewhich encodes the glycogen branching enzyme, on chromosome 3p Endomyocardial biopsy showed abundant PAS-positive, diastase-resistant cytoplasmic deposits gluucogenosis were also seen in muscle, skin, and liver specimens.

Neonatal type IV glycogen storage disease associated with “null” mutations in glycogen branching enzyme 1.

They also reported a striking reduction in lymph node deposits of glucocerebrosidase in patients with Gaucher disease after transplantation. Genetic counseling should be offered. The genes and proteins of atherogenic lipoprotein production. Of the 18 individuals with GSD IV who have received a liver transplant to date, two required a second liver transplant and six died: Utilizamos cookies para asegurar que damos la mejor experiencia al usuario en nuestro sitio web.

Diagnosis is based on clinical presentation, and glycemia and lactacidemia levels, after a meal hyperglycemia and glucogenosisglucogenosis after three to four glucovenosis fasting hypoglycemia and hyperlactacidemia. Without liver transplantation, death from liver failure usually occurs by age five years. Osteoporosis may require bisphosphonates. Decreased fetal movements, polyhydramnios, and fetal hydrops that may be detected prenatally; arthrogryposis, severe hypotonia, muscle atrophy at birth, early neonatal death.


Differential diagnoses for the childhood neuromuscular subtype of GSD IV include muscular dystrophies e. If cardiomyopathy was not observed on the baseline screening echocardiogram at the time of initial diagnosis, repeat echocardiograms are recommended every three months during infancy, every six months during early childhood, and annually thereafter.

Adult polyglucosan body disease: Death usually occurs in the neonatal period frequently due to cardiopulmonary compromise. Brown and Brown described successful prenatal testing for GSD IV based on levels of branching enzyme activity in cultured amniotic fluid cells and cultured chorionic villi.

An expanding view for the molecular basis of familial periodic paralysis.

The 5 other recipients were healthy and had normal liver function 16 to 73 months after transplantation. Congenital type IV glycogenosis: AMD represents a wide spectrum gluogenosis clinical presentations caused by an accumulation of glycogen in lysosomes: Differential Diagnosis Differential diagnoses for the perinatal and congenital neuromuscular subtypes of GSD IV include spinal muscular atrophyPompe diseaseZellweger syndromeand congenital disorders of glycosylation.

J Inherit Metab Dis. A bonus to all MIMmatch users is the option to glucogeonsis up for updates on new gene-phenotype relationships.

Death occurred at ages 4 months and 4 weeks, respectively, due to cardiorespiratory failure. Differential diagnoses include galactosemia, hydrops fetalis, tkpo tyrosinemia see these terms.

Fatal infantile neuromuscular presentation of glycogen storage disease type IV. The longest survival was 73 months in a patient who received a transplant at the age of 31 months. One infant had equinovarus feet with flexion contractures.

Li et al [] recently reported two unrelated infants with this subtype of GSD IV who were also small for gestational age. The diagnosis of glycogen storage disease type IV GSD IV is suspected based on the clinical presentation and the finding of abnormally branched glycogen accumulation in muscle or liver tissue.
