Constitutional del(19)(q12q13.1) in a three-year-old girl with severe phenotypic abnormalities affecting multiple organ systems

Am J Med Genet. 1998 Jun 5;77(5):391-4.


We present the clinical, cytogenetic, and molecular studies on a constitutional deletion of 19q ascertained prenatally due to decreased fetal activity and IUGR. Chromosome analysis by GTG banding on amniocytes suggested a del(19)(q13.1q13.3), but the analysis of microsatellites by PCR demonstrated that the deletion involved the distal segment of q12 and the proximal segment of q13.1 (15 cM). The severely affected female infant born at 38 weeks has clinical findings that may be related to haploinsufficiency of specific genes within 19q12.1-->q13.1 that control important processes of normal development and cell function.
