ABSTRACT
<p><b>OBJECTIVE</b>To analyze the chromosome aberration in a full-term male neonate with low birth weight, and to explore the possible causes for growth retardation in intrauterine development for the neonate.</p><p><b>METHODS</b>Genomic DNA was extracted from peripheral leukocytes of the neonate. Detection of genomic DNA copy number gain and loss was performed using microarray comparative genomic hybridization. Chromosome karyotype was obtained from cultured lymphocytes for the neonate and his parents in order to identify the origin of chromosome aberration.</p><p><b>RESULTS</b>Gain of 10q25.2-->qter (22 Mb) was observed in the full-term neonate with low birth weight. In addition, one chromosomal region, 15q26.2-->qter (5 Mb) was lost. The karyotype of the neonate was 46, XY, -15, +der(15), t(10;15)(q25;q26)pat.</p><p><b>CONCLUSION</b>The full-term neonate with low birth weight had a partial trisomy of 10q25.2-->qter with a partial monosomy of 15q26.2-->qter, both of them may contribute to the growth retardation in intrauterine development for the neonate case.</p>
