Treatment

Prognosis

  • Prognosis he prognosis depends on the malformations (cardiac, cerebral or intestinal) associated with the 2q37 deletion. The documents contained in this web site are presented for information purposes only.[orpha.net]
  • Such deletions may lead to an overall poorer prognosis than that of isolated cases of CDH without genomic alterations.[omicsonline.org]
  • Prognosis Long-term prognosis appears normal for GHRD, and postreceptor defects with the exception of STAT5b.[emedicine.medscape.com]

Etiology

  • At around 3 months of age, she developed cholestasis that was of uncertain etiology. Biliary imaging showed hepatomegaly, and hepatic scan showed severe hepatobiliary dysfunction indicative of biliary atresia.[nature.com]
  • It is the commonest syndrome featuring CDH as a cardinal feature with an estimated 10% of patients with CDH having FS. [3] The exact genetic etiology is yet to be established.[jdrntruhs.org]
