Two unrelated children, not affected with Down's syndrome, with strikingly similar phenotypes and an extra G-like chromosome are presented. Quinacrine and trypsin-Giemsa banding identified the extra chromosome as No. 22. The phenotype of these patients and the review of 15 additional similar cases from the literature permit a definition of the cardinal features of trisomy 22; mental and growth retardation, microcephaly and craniofacial asymmetry, strabismus, beaked and prominent nose, long philtrum, cleft palate, micrognathia, large low set ears with preauricular tags and/or pits, long slender fingers, congenital heart disease, inguinal hernia, and hip dislocation.

A patient identified as being a partial trisomy 22 mosaic is presented. The presence of a translocation t(4;22) (pter;q12) is noted in the mother, sister and maternal aunt. Comparison is made with nine other reported cases of partial trisomy 22 confirmed by parental translocation. These suggest a definite syndrome, including mental retardation, congenital heart disease, skeletal anomalies, anti-mongoloid slant of the palpebral fissures, preauricular skin tags and low-set ears.

A case of trisomy 22 liveborn female baby with multiple congenital anomalies is described. Physical manifestations included failure to thrive, hypotonia, pre-auricular sinus, low set ears, hypertelorism, posterior low hair line, micrognathia, cleft palate, congenital heart disease, imperforated anus with anovulvar fistula, contracted pelvis and bilateral rocker-bottom feet. The infant died at two months of age. Cases of trisomy 22 usually present with many severe malformations, and they rarely survive to term. A review of the literature is presented to delineate this chromosome disorder.

We present an infant with true trisomy 22. Mosaicism is ruled out by the finding of a 47,XX, +22 karyotype in all cells analysed originating from two embryonic germ layers. The physical findings are consistent with the previously noted features including developmental delay, ear abnormalities, micrognathia, clefting, and congenital heart disease. The patient is the first described with macrocephaly and hydrocephalus and the second with holoprosencephaly.

Atrioventricular septal defect also known as endocardial cushion defect is severe congenital heart disease which is often associated with chromosomal abnormalities (30-50%) or is a part of a malformation syndrome (30%). Between 1, october 1992, and 30, september 1996. 21 cases were diagnosed prenatally. The chromosomal analysis found in 1 case trisomy 18, in 1 case trisomy 22 and in 7 cases trisomy 21. In 7 cases atrioventricular septal defect was part of Ivemark syndrome, none of them had chromosomal abnormality, except 1, who had trisomy 18. Out of 21 cases there was only one survivor. None of cases associated with Ivemark syndrome survived. In 4 cases sibs or parents had congenital heart disease. Four mother were above 40 years. The report summarises the most important abnormalities in the prenatal diagnosis of endocardial cushion defect and echocardiographic and embryopathologic foundings.

Trisomy 22 is the third most common autosomal trisomy occurring in about 0.4% of all clinically recognized pregnancies. Complete non-mosaic trisomy 22 is extremely rare in live births. Most affected children die before one year of age. To date, only 29 liveborn cases have been reported and none has carried an additional genetic lesion. In this report, we describe the clinical presentation, cytogenetic, and cytogenomic findings in a liveborn female with complete non-mosaic trisomy 22 as well as a paternally inherited, balanced reciprocal chromosomal rearrangement t(4;6)(q33;q23.3). The proband manifested features commonly seen in individuals with non-mosaic trisomy 22 such as intrauterine growth retardation (IUGR), single umbilical artery, cranial abnormalities, short neck, cleft lip and palate, dysmorphic ears, hypoplastic nipples, digital malformation, congenital heart defects, dysplastic kidneys, and genital anomalies. In addition, she had lobar holoprosencephaly, aqueductal stenosis, and limb and eye problems that have not been associated with complete trisomy 22 in previous reports. She died at 35 days of age of complex heart disease and renal failure. We are hereby expanding the cytogenetic and clinical spectrum of this rare chromosome disorder. Clinical features of liveborn children with non-mosaic trisomy 22 are reviewed and compared to those in our proband. The impact of genomic content in relation to the survival of trisomies in humans is also discussed.
