Failure to Thrive
Mutations were also found in patients with atypical clinical signs such as intestinal malabsorption, failure to thrive, the absence of hepatomegaly, or renal hyperfiltration. [ncbi.nlm.nih.gov]

Osteoporosis
Generalized osteopenia leading to fractures during childhood, with osteoporosis later in life, has also been reported. Some patients also display an abnormal fat distribution. [orpha.net]
Untreated patients usually complain of growth failure, osteoporosis, rickets, nephrolithiasis and eventually renal insufficiency. [scinapse.io]
Long-term complications include gout, hepatic adenomas, osteoporosis, renal disease, and short stature. Major progress has been made in managing this disorder. [ommbid.mhmedical.com]

Amino Acids Increased
All patients showed symptoms of catabolism, such as hypoglycaemia, ketonuria, ketonaemia, decreased serum levels of the glucoblastic amino acids, increased serum levels of the branched chain amino acids, triglycerides, free fatty acids, phospholipoids [slideheaven.com]
Treatment
Management and treatment Treatment of FBG is symptomatic revolving around compensation of the renal syndrome with replacement of water and electrolytes. Vitamin D and phosphate supplements are essential for preventing hypophosphatemic rickets. [orpha.net]
Symptomatic treatment is directed towards a stabilization of glucose homeostasis and compensation for renal losses of various solutes. [doi.org]
However, with the proper treatment, some of the symptoms of Fanconi Bickel syndrome can resolve with age. [rarediseases.info.nih.gov]
Prognosis
Prognosis The long-term prognosis is unknown. The renal tubular dysfunction persists into adulthood but in most cases does not appear to progress to renal failure. [orpha.net]
Conclusion: Long term prognosis of Fanconi-Bickel syndrome is unknown, the renal tubular dysfunction persists into adulthood but in most cases does not appear to progress to renal failure. [journalofpediatriccriticalcare.com]
Prognosis : mostly death by age 4, due to cirrhosis and portal hypertension. Type V: McArdle's disease See the separate article on McArdle's Glycogen Storage Disease. [patient.info]
Etiology
Etiology FBG is caused by homozygous or compound heterozygous mutations in the SLC2A2 gene (3q26.2-q27). [orpha.net]
Etiology The etiology of GSD is best understood by following the metabolic events leading to the synthesis (glycogenesis) and degradation of glycogen (glycogenolysis). [knowledge.statpearls.com]
Ongoing controversies regarding etiology, diagnosis, treatment In 2002, guidelines from the European Study on Glycogen Storage Disease Type I (ESGSDI) recommended liver transplantation in patients with type I GSD and unresectable hepatocellular adenomas [clinicaladvisor.com]

In addition to the clinical and molecular genetic aspects of FBS, this review discusses the pathophysiology of the disease and compares it to recent findings in GLUT2 deficient transgenic animals. [eurekaselect.com]
Prevention
Vitamin D and phosphate supplements are essential for preventing hypophosphatemic rickets. Patients should follow a galactose-restricted diabetic diet with fructose as the main source of carbohydrate. Prognosis The long-term prognosis is unknown. [orpha.net]
Because people with Fanconi Bickel syndrome have trouble moving glucose throughout the body, limiting galactose prevents the buildup of glucose and glycogen in the liver and kidneys. [rarediseases.info.nih.gov]
Uncooked (raw) cornstarch (1-1.5 grams per kg) administered at bedtime prevents morning hypoglycemia and ketosis. Daytime hypoglycemia tends to be mild and snacks every 2 to 4 hours prevent hypoglycemia. [clinicaladvisor.com]
