Gastrointestinal abnormalities in the syndrome of mosaic trisomy 9

The proband, an 18 month old child, was delivered by caesarian section after an uneventful 38 week gestation, birth weight 2400 g. Cytogenetic studies performed on peripheral blood lymphocytes, cultured with phytohaemagglutinin for 72 hours, indicated that 70 out of 100 cells (70%) had a normal fema...

Zusammenfassung:	The proband, an 18 month old child, was delivered by caesarian section after an uneventful 38 week gestation, birth weight 2400 g. Cytogenetic studies performed on peripheral blood lymphocytes, cultured with phytohaemagglutinin for 72 hours, indicated that 70 out of 100 cells (70%) had a normal female karyotype (46,XX) and 30 cells (30%) were trisomic for chromosome 9, 47,XX,+9.
