ABSTRACT
OBJECTIVE To analyze a neonate with multiple malformations and to correlate its genotype with phenotype. METHODS The karotypes of the child and her parents were subjected to G-banding chromosome analysis, and array comparative genomic hybridization (array-CGH) was used for fine mapping of the aberrant region. RESULTS The karyotype of the child was ascertained as 46,XX,del(18)(p11.2). Array CGH has identified a 9.8 Mb deletion at 18p11.32-p11.22. The patient has presented features such as holoprosencephaly, choanal atresia, heart defect, and craniofacial dysmorphisms. CONCLUSION The de novo 18p deletion probably underlies the main clinical manifestations of the child.
