He presented at 6 months with hypoglycaemia, failure to thrive and hypertransaminasaemia. He subsequently developed an enteropathy with subtotal villous atrophy on biopsy. [ncbi.nlm.nih.gov]
Feeding difficulties can lead to a failure to gain weight and grow slower than normal (failure to thrive). Ocular abnormalities, sensorineural hearing loss, cardiac abnormalities and skeletal dysplasias are possible. [fcdgc.rarediseasesnetwork.org]

Other features include pleural effusions, osteopenia, recurrent fractures, kyphosis, dystrophic limbs, weakness, and joint contractures. [accessanesthesiology.mhmedical.com]
Osteopenia or osteoporosis was present in all patients of our cohort, sometimes with severe clinical implications. [ojrd.biomedcentral.com]
Adults with PMM2-CDG may live until their 7th or 8th decades with stable cognitive delay, peripheral neuropathy, and progressive thoracic and spinal kyphoscoliosis with osteopenia or osteoporosis (34). [ncbi.nlm.nih.gov]
As a rule there is osteopenia. A very common feature is cerebellar hypoplasia, which can usually be documented at or shortly after birth. [nature.com]

Hydrops fetalis was noticed in 3, edemas in 11/13; gastrointestinal symptoms in 9/14; structural brain pathology, psychomental retardation, seizures, ataxia in 12/13, muscle hypotonia in 13/14. [ojrd.biomedcentral.com]

- Renomegaly
ANALYZED: R83C, Q347X CARRIER FREQUENCY: 1 in 71 (Ashkenazi Jewish) MODE OF INHERITANCE: autosomal recessive Glycogen storage disease Type 1A (GSD1A) is a metabolic condition that when untreated, often results in severe hypoglycemia, seizures, hepato- and renomegaly [chginc.org]
Workup
Conclusion We confirm that CDG screening should be a part of the routine workup of adolescent/adult patients with sporadic or presumably autosomal recessive cerebellar ataxia, even in the absence of other suggestive signs. [ojrd.biomedcentral.com]
Thus, SYCP3 testing may be considered in the workup for women with recurrent pregnancy loss, and in males with non-obstructive azoospermia. Our laboratory offers DNA sequencing of all coding exons (2-9) of the SYCP3 gene. [chginc.org]
Angiography
- Mural Thrombus
The portal vein was partially occluded by a mural thrombus. The graft functioned immediately. The aneurysms were not amenable to surgery during transplantation. [pediatrics.aappublications.org]
Microbiology
- Staphylococcus Aureus
Staphylococcus aureus causes most liver abscesses in patients with CGD. Often the liver abscesses are hard to drain and may need surgery. [primaryimmune.org]
Subsequently Staphylococcus aureus sepsis attributable to a splenic abscess occurred that was treated by CT-guided drainage and prolonged administration of antibiotics. [pediatrics.aappublications.org]
She had severe recurrent stomatitis, recurrent otitis media and externa, perianal and perirectal abscesses, and, at the age of 12 years, 2 brain abscesses due to Staphylococcus aureus. [lymphedemapeople.com]
Treatment
Early diagnosis and treatment during infancy can improve prognosis; however, liver cirrhosis can still impact life expectancy. Treatment Treatment for CDG Type 1B involves life-long management with high doses of oral mannose therapy. [evolvegene.com]
Treatment with d-mannose is the only described therapy for CDG Ib. We have extablished the diagnosis in 2 patients. [adc.bmj.com]
Treatment options are being explored to facilitate glycosylation with either a membrane-permeable mannose-1-phosphate treatment or enzyme replacement therapy. [digitalcommons.hsc.unt.edu]
Prognosis

Generally, the prognosis will vary depending on the severity of symptoms and their response to mannose treatment. [counsyl.com]
Treatment and Prognosis To date, there are no known specific treatment options for ALG12-CDG. Treatment is aimed at the management of symptoms and the prevention of complications. Some ALG12-CDG patients die within the first years of life. [fcdgc.rarediseasesnetwork.org]
What is the prognosis for a person with Congenital Disorder of Glycosylation Type Ia? Twenty percent of people with CDG-Ia die within the first year of life, often due to infection, liver problems, or heart disease. [myriadwomenshealth.com]
