Case 3 (P3, Figure 1D ) is an 11 years old girl of Turkish origin. She presented with delayed motor development at the age of 3 years. Brain MRI was normal. She showed slight facial dysmorphism, hypermobility of the joints and skin laxity. [journals.plos.org]
Recently, the reports of a Turkish patient with CDG-IIc ( 80 ) and of a patient of consanguineous Brazilian descent ( 81 ) were valuable. [nature.com]

Failure to Thrive
Feeding difficulties leading to failure to thrive is also common. Failure to thrive is defined as the failure to grow and gain weight as would be expected based upon age and gender. [rarediseases.org]
It is characterized by sparse, kinky hair; failure to thrive; and progressive deterioration of the nervous system. [checkrare.com]
The diagnosis should be considered in all patients with failure to thrive, mental retardation, cerebellar hypoplasia, liver dysfunction, or stroke-like episodes. [egl-eurofins.com]
Additionally, these individuals have severe failure to thrive after birth. [themedicalbiochemistrypage.org]
At the age of 8 months she presented with hypotonia, failure to thrive, microcephaly, general developmental delay, hepatosplenomegaly and flexion contractures of all fingers. There was no facial dysmorphism. [ojrd.biomedcentral.com]

No curative or effective treatment is available for neurological CDG. Since at least 1% of the genome is involved in glycosylation, it is likely that the large majority of CDG is yet to be discovered. [books.google.it]

Prognosis Infections in LAD-II are rarely life-threatening and thus patients may live to adulthood. The documents contained in this web site are presented for information purposes only. [orpha.net]
Affected individuals should talk to their physician and medical team about their specific case, associated symptoms and overall prognosis. [rarediseases.org]
Etiology
Etiology LAD-II is a carbohydrate-deficient glycoprotein syndrome (CDG syndrome; see this term) and is therefore also referred to as CDG IIc. [orpha.net]
The diagnosis of CDGs should be suspected in cases with neurological signs and symptoms of unknown etiology, or in any patient with multisystemic disease even in the absence of neurological features. [clinicaltrials.gov]
The differential diagnosis of abnormal transferrin patterns also includes liver disease not related to CDG including galactosemia, hereditary fructose intolerance in acute crisis, and liver disease of unexplained etiology. [mayomedicallaboratories.com]

However, more work is needed to pinpoint the exact function of MAN1B1 in glycoprotein quality control, and to understand the pathophysiology of its deficiency. [journals.plos.org]
Others, such as muscle-eye-brain disease and Walker–Warburg syndrome, were well known, but elucidation of their relation to glycosylation has provided new insights into their pathophysiology and opens possibilities for therapy. [clinicalgate.com]
RESULTS Subcellular localization of the wt and mutated transiently expressed TMEM165 proteins Determination of the subcellular localization of wt and mutant TMEM165 was undertaken to further understand the pathophysiology of the CDG linked to this protein [doi.org]

Health concerns can be decreased through preventative medicine with appropriate nutrition and scheduled immunizations. Doctors and scientists are working to find and create more specific treatments for CDG. CDG CARE supports these research efforts. [cdgcare.com]
