We report on a prenatal diagnosis by FISH of a familial 22q11 deletion associated with DiGeorge syndrome (DGS). The deletion was seen in the proband with symptoms of full DGS, in the physically normal father, and in a subsequent pregnancy. After birth this child showed hypocalcaemia, a T cell deficit, and a right sided aortic arch.
Microdeletion of 22q11 is responsible for DiGeorge syndrome, velocardiofacial syndrome, congenital conotruncal heart defects, and related disorders. We report our experiences on prenatal diagnosis by fluorescence in situ hybridization (FISH) for 22q11 deletion in two fetuses with tetralogy of Fallot. Karyotyping and FISH of the parents revealed that one fetus inherited the disease from maternal...
The 22q11 region has been implicated in chromosomal rearrangements that result in altered gene dosage, leading to three different congenital malformation syndromes: DiGeorge syndrome, cat-eye syndrome (CES), and der(22) syndrome. Although DiGeorge syndrome is a common genomic disorder on 22q11, CES is quite rare, and there has been no report of Korean CES cases with molecular cytogenetic confir...
The 22q11.2 microdeletion syndrome (22q11.2 DGS) is characterized by an extreme intrafamilial and interfamilial variability. main clinical features are congenital heart defects, palatal abnormalities, learning disability, facial dysmorphisms immune deficiency. In 85–90% of cases, the DGS caused a heterozygous ~3-Mb deletion, including TBX1 gene, considered one major genes responsible for defect...
BACKGROUND Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is characterized by congenital aplasia of the uterus and the upper part of the vagina in women showing normal development of secondary sexual characteristics and a normal 46, XX karyotype. The uterovaginal aplasia is either isolated (type I) or more frequently associated with other malformations (type II or Müllerian Renal Cervico-thorac...
