Authors have had the opportunity to study a patient affected by a malformative syndrome with severe motricity and mental retardation. Physical findings (namely: spacious forehead, flat and round face, small palpebral fissures, hypotonicity and growth retardation) are similar to the phenotype previously described in trisomy 10q. Chromosomal diagnosis failed until G, Q and R banding technique was applied. With this technique a partial 10q trisomy (q24 leads to q ter) due to a maternal translocation t(6:10)(q26;q24) was found.

Objective: To explore the clinical phenotype and pathogenesis of a child with partial duplication in the long arm of chromosome 10 (10q), and conduct a review of relevant literature.
Methods: A child presented at Lianyungang Maternal and Child Health Care Hospital in April 2018 for growth retardation, intellectual disability, and autism spectrum disorder (ASD) was selected as the study subject. Peripheral blood samples were collected from the child and his parents for G-banded chromosomal karyotyping analysis.

Background: Chromosome aberrations of 10p monosomy and 10q trisomy resulting from parental pericentric inversion 10 are extremely rare, and to date, very few reports have been published on the matter.
Case Presentation: A 30-year-old pregnant woman with recurrent pregnancy loss is enrolled in this research. In this pregnancy, spontaneous abortion occurred in the first trimester of her pregnancy.

We present a complex chromosomal anomaly identified using cytogenetic and molecular methods. The child was diagnosed during the neonatal period with a multiple congenital anomalies syndrome characterized by: flattened occipital region; slight turricephaly; tall and broad forehead; hypertelorism; deep-set eyes; down slanting and short palpebral fissures; epicanthic folds; prominent nose with wide root and bulbous tip; microstomia; micro-retrognathia, large, short philtrum with prominent reliefs; low set, prominent ears; and congenital heart disease. The GTG banding karyotype showed a 46,XY,der(10)(10pter→10q26.

The phenotype of an unbalanced translocation is characterized by the dosage effects of the affected genes in the translocated chromosome. We present the case of a fetus with a paternally derived unbalanced 46,XY,der(10)t(6;10)(p22;q26.1) translocation, detected following growth retardation and cardiac malformation.

The phosphatase and tensin homolog () gene is a tumor-suppressor gene located on 10q22-23. Since the introduction of molecular genetics in prenatal diagnostics, various birth defects associated with gene mutations have been diagnosed. However, no reports on fetal cases related to mutation have been found, so far.
