Prenatal Diagnosis of 2q32 Deletion Syndrome Characterized by Multiple Segmental Deletions and Complex Chromosomal Rearrangement Involving Chromosomes 2, 5 and 7

Heidi L Thorson et al. Fetal Diagn Ther. .

Abstract

This is the first case of 2q32 microdeletion syndrome diagnosed prenatally and followed throughout the pregnancy. The pregnancy was complicated by fetal club feet, ventriculomegaly, intrauterine growth retardation and polyhydramnios. This is a unique and highly complicated prenatal diagnosis case of a de novo complex chromosomal rearrangement involving chromosomes 2, 5 and 7 with 15 breaks and multiple interstitial 2q deletions, resulting in the 2q32 microdeletion syndrome. The delineation of the karyotype in this case and origin of the pathology required the use of multiple genetic technologies including conventional cytogenetics, fluorescence in situ hybridization, single-nucleotide polymorphism array and array comparative genomic hybridization.
