De Novo Deletion of Chromosome 20q13.33 in a Patient with Tracheo-esophageal Fistula, Cardiac Defects and Genitourinary Anomalies Implicates GTPBP5 as a Candidate Gene

چکیده
BACKGROUND Tracheo-esophageal fistula (TEF) with/or without esophageal atresia (EA) is a common congenital malformation that is often accompanied by other anomalies. The causes of this condition are thought to be heterogeneous but are overall not well understood. CASE REPORT We identified a patient with a TEF/EA, as well as cardiac and genitourinary anomalies, who was found to have a 0.7 Mb de novo deletion of chromosome 20q13.33. One gene within the deleted interval, GTPBP5, is of particular interest as a candidate gene. CONCLUSIONS GTPBP5 bears further study as a cause of TEF/EA accompanied by other malformations.

Esophageal atresia with/without tracheo-esophageal fistula is a relatively common malformation, occurring in around 1 in 3500 births. In around half of cases, additional malformations are present, forming either a syndrome of known genetic aetiology, or a recognised association, of which the VACTERL association (Vertebral anomalies, Anal atresia, Cardiac malformations, Tracheo-Esophageal fistul...

The common causes of 18p deletion syndrome are spontaneous errors in the chromosomal structure in the early stages of human embryonic development. In this study, a 29-year-old girl was introduced with the features of deletion of chromosome 18. In addition, GTG banding karyotype revealed that this case had a deletion involving the short arm of chromosome 18. In comparison with the usual phenotyp...

Thirty-four cases (29 children and five adults) of congenital absence of the gall bladder were found in a retrospective necropsy study. When the distribution of associated malformations in these patients was analysed, the cases were found to fall into several groups. The largest group (13) had multiple anomalies involving the genitourinary (83% reproductive tract, 42% renal), gastrointestinal (...

VACTERL association is a rare disorder with various congenital malformations. The aetiology remains unknown. Combination of at least three congenital anomalies of the following criteria is required for diagnosis: vertebral defects, anal atresia, cardiac anomalies, tracheo-esophageal fistula, renal anomalies, and limb defects. The first case was 1-day old male neonate with multiple congenital an...
