A rare mosaic 22q11.2 microdeletion identified in a Chinese family with recurrent fetal conotruncal defects.

Abstract:

BACKGROUND:22q11 deletion syndrome (22qDS) is caused by deletion of chromosome region 22q11.2. However, mosaic cases with 22q11.2 deletion syndrome (22q11.2DS) are rarely reported. METHODS:Chromosomal microarray analysis (CMA) and fluorescence in situ hybridization fluorescence in situ hybridization (FISH) were performed to analyze the copy number alterations. Clinical examinations related to 22q11.2DS were performed on the carrier in this family. RESULTS:A healthy female in a Chinese family with a history of two pregnancies with conotruncal defects, one with pulmonary atresia (PA) and another with Tetralogy of Fallot (TOF) was recruited in this study. CMA revealed that the fetus with TOF has a microdeletion on the 22q11.2 locus, and his mother was further confirmed a somatic mosaicism of 22q11.2 microdeletion by interphase FISH. Somatic mosaic 22q11.2 deletion in the mother was validated in the metaphase lymphocytes. Clinical examinations related to 22q11.2DS showed that the mother had hypocalcemia and low percentages of CD4 + T helper cells. The family history of recurrent fetal conotruncal defects and genetic results demonstrated the inherited possibility of maternal germline mosaicism of the 22q11.2 microdeletion. CONCLUSION:Our report was the first case in a Chinese family to present that a somatic and suspected gonadal mosaicism of the 22q11.2 microdeletion in female causes recurrent fetal conotruncal defects.
