Catch 22 Digeorge Syndrome
Catch 22 digeorge syndrome. Main problem is related to the immune system due to aplasia of the thymus T cells are unable to mature. DiGeorge syndrome also known as 22q112 deletion syndrome is a genetic disorder caused by a small deletion in chromosome 22 at position. We report the clinical findings in 44 cases.
CATCH 22 syndrome 22q112 deletion syndrome also called DiGeorge syndrome and velocardiofacial syndrome is a disorder caused by the deletion of a small piece of chromosome 22. Wereport the clinical find-ings in 44 cases. DiGeorge syndrome is sometimes described as one of the CATCH 22 disorders so named because of their characteristicscardiac defects abnormal facial features thymus underdevelopment cleft palate and hypocalcemiacaused by a deletion of several genes in chromosome 22.
We propose that DiGeorge syndrome should be seen as the severe end of the clinical spectrum embraced by the acronym CATCH 22 syndrome. 131 rows 22q112 deletion syndrome is caused by a missing piece deletion of part of. Abnormal facies hypertelorism low set ears short philtrum among others T.
Congenital heart disease particularly conotruncal anomalies A. Cardiac defects Abnormal facies Thymic hypoplasia Cleft palate and Hypocalcaemia resulting from 22q11 deletions. We propose that DiGeorge syndrome should be seen as the severe end of the clinical spectrum embraced by the acronym CATCH 22 syndrome.
The deletion occurs near the middle of the chromosome at a location designated q112. It results in almost all cases from a deletion within chromo-some22qll. It results in almost all cases from a deletion within chromosome 22q11.
The DiGeorge anomaly DGA originally considered a clinical paradigm for isolated thymus deficiency has now been redefined as a member of a group of disorders that share in common a chromosome deletion which results in monosomy 22q11 CATCH-22 or DiGeorgevelocardiofacial VCFS syndrome. 9 The underlying disorder is microdeletion in the 22q112 region of the 22nd chromosome but the pathophysiology is not fully understood. DiGeorge syndrome DGS comprises thymic hypoplasia hypocalcaemia outflow tract defects of the heart and dysmorphic facies.
A mnemonic to remember the manifestations of 22q112 deletion syndrome DiGeorge syndrome is. Part of CATCH 22 DiGeorge syndrome DGS comprises thymic hypoplasia hypocalcaemia outflow tract defects of the heart and dysmorphic facies.
It results in almost all cases from a deletion within chromosome 22q11.

Part ofCATCH22 DI Wilson J Burn PScambler J Goodship Abstract DiGeorge syndrome DGS comprises thymic hypoplasia hypocalcaemia out-flow tract defects ofthe heart and dys-morphic facies. DiGeorge syndrome also known as 22q112 deletion syndrome is a syndrome caused by the deletion of a small segment of chromosome 22. We propose that DiGeorge syndrome should be seen as the severe end of the clinical spectrum embraced by the acronym CATCH 22 syndrome. We report the clinical findings in 44 cases. We propose that DiGeorge syndrome should be seen as the severe end of the clinical spectrum embraced by the acronym CATCH 22 syndrome.

DiGeorge syndrome also known as 22q112 deletion syndrome is a syndrome caused by the deletion of a small segment of chromosome 22. 9 The underlying disorder is microdeletion in the 22q112 region of the 22nd chromosome but the pathophysiology is not fully understood. CATCH 22 mnemonic for DiGeorgesyndrome. It results in almost all cases from a deletion within chromo-some22qll. The estimated incidence of DiGeorge syndrome is approximately 1 in 40006000 live births. Main problem is related to the immune system due to aplasia of the thymus T cells are unable to mature.
