Over the last decade, several advances in ultrasound techniques, increasing availability of whole genome microarray testing, and overall expansion of our knowledge about the human genome have drastically enhanced our ability to detect chromosomal abnormalities prenatally. Despite that, genotype–phenotype correlation is difficult to establish for many chromosomal aberrations, particularly for those that are rare, as it requires thorough analysis of a significant number of cases. This in turn increases the burden of the obstetric provider to appropriately counsel a patient regarding prognosis and pregnancy options in these complicated situations. Our experience in prenatal diagnosis and management of a fetus with multiple anomalies and partial trisomy for the 14q11–q24.2 prompted a comprehensive analysis of the relevant literature. Although complete non-mosaic trisomy 14 is associated with first trimester miscarriages, partial trisomy 14q is a rare condition with undefined genotype–phenotype correlation, preventing accurate prenatal counseling, and informed decision making. We performed a systematic literature review, that aimed to summarize prenatal and postnatal findings of individual case reports on 51 patients with partial trisomy 14q in order to elucidate genotype–phenotype correlation, and to supply healthcare professionals with recommendation on essential fetal and parental testing for accurate diagnosis, pregnancy outcomes, and proper family counseling. Comparison of the clinical findings among the patients with partial 14q trisomy suggest that the resulting phenotype is likely to be influenced by the extent of the 14q trisomy segment, associated chromosomal imbalances, parental origin of the rearrangement, and dosage of the genes within the imprinted 14q32 cluster. © 2016 Wiley Periodicals, Inc.
