In fact, only two of the four cases from the literature with CDH and 11p duplication presented with BWS [11, 13]. [frontiersin.org]

Most authorities have suggested that the extra chromosome is present because of nondisjunction. [ojrd.biomedcentral.com]

He had a very prominent, large nose, noticeable as a young child, with a convex nasal bridge and anteverted nostrils, present to a much lesser degree in his father. [jmg.bmj.com]

Causes In individuals with Chromosome 11, Partial Trisomy 11q, the end (distal) region of the long arm (q) of chromosome 11 is present three times (i.e., trisomic or duplicated) rather than twice in cells of the body. [rarediseases.org]

• Hepatosplenomegaly

• Poor Coordination

  Developmental delay was apparent with mild hypotonia as an infant, a delay in motor activity with walking achieved at 3 years, and poor coordination. [jmg.bmj.com]

Hence, a genetic workup should be performed in patients with CDH, particularly when another phenotypical abnormality is noted. [frontiersin.org]

Standard Therapies Treatment Treatment of Chromosome 11, Partial Trisomy 11q is symptomatic and supportive. [rarediseases.org]

Eventually, the patient suffered a sepsis requiring aggressive treatment including catecholamines, intensive ventilation, and antibiotic therapy. Despite all measures, pulmonary and cardiac failure progressed. [frontiersin.org]

The prognosis is variable. A child with trisomy 18 has an estimated risk to develop Wilms tumor of about 1%[86]. [ojrd.biomedcentral.com]

However, in approximately 70% of patients, the etiology of CDH remains unknown [7]. [frontiersin.org]
