Two fourth cousins with a strikingly similar pattern of malformation and who have an unbalanced translocation (46, XY, -17, +t (17p; 10q) are described. From an analysis of the phenotypes of these patients and others reported with 10q trisomy, we propose that the trisomy 10q 24-26 syndrome includes: growth and mental retardation, a characteristic facies (microcephaly, flat face with spacious forehead, small nose, depressed nasal bridge, arched wide-spaced eyebrows, blepharophimosis, microphthalmia, low-set ears, bow-shaped mouth with prominent upper lip, micrognathia), palate anomalies (high-arched cleft or agenesis), congenital heart disease, and anomalies of the hands and feet. Anomalies common to the cousins, but not described in other patients with trisomy 10q, are believed to be expressions of a partial monosomy of 17p.

Partial trisomy of the 10q region was originally reported in 1979 [1]. For 25 years, the diagnosis was made microscopically based on large, visible insertions in the region identified by karyotype analysis. Previous case reports have included both unbalanced translocations and large duplications/insertions in the 10q region [2]. Probands with partial trisomy 10q syndrome often have an abnormal phenotype that may include developmental delay [3-5], craniofacial abnormalities [3, 5], talipes (clubfoot) [2], microcephaly [2-4], or congenital heart disease [2-6]. Prenatal diagnoses by karyotype have been made following ultrasound diagnosis of sacrococcygeal teratoma [7], renal pyelectasis [3, 8-10], and other fetal abnormalities [4]. In this case, we report the first prenatal diagnosis of partial trisomy 10q (10q22.3-10q23.2) with a normal karyotype and an abnormal chromosomal microarray analysis (CMA). This is the smallest copy number variant (CNV) (7.5 Mb) in the 10q22.3-10q23.2 regions yet reported.
