Presentation
Upper extremity differences that are present at birth are called congenital abnormalities or disorders. These differences may range from mild, such as constriction bands on the fingers, to severe, such as part of an arm remaining unformed. [lihandtoshouldercenter.com]
is a congenital problem, which means that it is present at birth. [kidspot.com.au]
The World Health Organization (WHO) describes a congenital disorder (CD) or birth defect as an abnormality in the structure or function of a person, which is present from birth. [geneticalliance.org.za]
A "birth defect" is a health problem or physical change, which is present in a baby at the time he/she is born. [ummchealth.com]

- Trisomy 21
The most well-known and common condition with a difference in chromosome number is Down syndrome (also known as trisomy 21). [centerforfetalmedicine.com]
Associations Congenital cardiac anomalies can be found with many aneuploidic conditions which include: trisomy 18 : up to 90% can have cardiac anomalies trisomy 13 : up to 90% trisomy 21 : up to 50% Turner syndrome : up to 40% Related Radiopaedia articles [radiopaedia.org]
Many zygotes that carry such abnormalities do not develop into embryos, but among those that are carried to term, trisomy 21 ( Down syndrome ), trisomy 13 (Patau syndrome ), and trisomy 18 (Edwards syndrome) are the most frequent birth defects. [nature.com]
Most people with non-mosaic Down syndrome have three copies of chromosome 21 in all of their cells (chromosome 21 trisomy); some have an extra copy of chromosome 21 attached to a different chromosome in all of their cells (chromosome 21 translocation) [ssa.gov]
- Cerebral Palsy
Pediatric neurosurgeons at UCSF also have vast experience with selective dorsal rhizotomy for cerebral palsy, and these patients are treated in conjunction with orthopaedic surgery, physical medicine/rehabilitation physicians, and ancillary specialists [neurosurgery.ucsf.edu]
Congenital disorders treated Our orthopaedists have the compassion and experience to treat a variety of congenital disorders, including: Cerebral palsy Muscular dystrophy Osteogenesis imperfecta ("brittle bone disease") Skeletal dysplasias (affects bone [ummchealth.com]

- Failure to Thrive
Some people have severe developmental delay, failure to thrive, and multiple organ problems, while others have diarrhea, low blood sugar ( hypoglycemia ), liver problems, and normal developmental potential. [2] Last updated: 9/21/2011 [rarediseases.info.nih.gov]
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]

Treatment
Treatment - Congenital disorder of glycosylation type 1C No treatment is available for most of these disorders. Resources - Congenital disorder of glycosylation type 1C Not supplied. [checkorphan.org]
People with very mild cases may not require treatment with a low-phenylalanine diet [omicsonline.org]
Therefore, both diagnosis and treatment should be organised in experienced centres. [erswhitebook.org]
PMI-CDG This is the only CDG that has an effective treatment. Individuals are given a specific sugar called mannose, which then can improve the glycosylation. This treatment has been successful in several cases of PMI-CDG. [cafamily.org.uk]
If the MRI scan shows any evidence of these malformations, a neurosurgical consultation is recommended to develop the best treatment plan. [hopkinsmedicine.org]

In addition, in cases where the natural history indicates a poor prognosis, orthotic treatment is contraindicated. [emedicine.medscape.com]

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. [counsyl.com]
Etiology
The etiology of these disorders will be studied using candidate gene analysis (primarily based on the PI3K/AKT pathway) and possibly exome and whole genome sequencing (done under protocol 10-HG-0065). [clinicaltrials.gov]
These lesions are usually soft tissue or bone abscesses, and the etiologic agents are typically staphylococci, gram-negative enteric species, or fungi. [ncbi.nlm.nih.gov]
Pathology These defects as a group have a heterogeneous etiology with many resulting from an interplay between both genetic and environmental factors. [radiopaedia.org]
With transverse or longitudinal deficiency, depending on the etiology, infants may also have hypoplastic or bifid bones, synostoses, duplications, dislocations, or other bony defects; for example, in proximal femoral focal deficiency, the proximal femur [merckmanuals.com]

The pathophysiology results from depressed synthesis or remodeling of oligosaccharide moieties of glycoproteins. The ultimate result is the formation of abnormal glycoproteins affecting their structure and metabolic functions. [ncbi.nlm.nih.gov]
