Trisomy 13 is a clinically severe entity; 85% of the patients do not survive beyond one year, and most children die before completing six months of age. We report a female child, 28 months old, white, the fourth child of a non-consanguineous couple, who presented trisomy 13. The child was born at term, from a vaginal delivery, weighing 2600 g. At birth, she was cyanotic, icteric, spastic, and cried weakly. The initial clinical examination detected polydactyly in the left hand, congenital clubfoot and convex soles, ocular hypertelorism, a low nasal bridge, numerous hemangiomas distributed throughout the body, cardiomegaly, and perimembranous inter-ventricular communication. There was no cleft lip or palate. On physical examination at 18 months old, the child weighed 6,900 g, had a cephalic perimeter of 41 cm, a thoracic perimeter of 43 cm and was 76 cm tall. At 28 months, she weighed 10,760 g and was 88.5 cm tall. Neuropsychomotor development retardation was evident from birth and, according to the psychologist and the social assistant of APAE (Handicapped Parents and Friends Association) in Canguçu, Rio Grande do Sul, there was a noticeable improvement after physiotherapy and recreational sessions.

The purpose of the study is to provide data about long-term survivors with full trisomy 13 (t13). Mothers of 30 long-term survivors with full t13 completed an online survey. Survey data were downloaded into an SPSS database. Descriptive statistics were used to analyze survey data. Tracking Rare Incidence Syndrome (TRIS) Survey data on survival, birth information including maternal and paternal age at conception, physical characteristics, and medical conditions were compared. Data indicate longer mean survival rates (48.4 months for those living at the time of data collection, 40.8 months for those who died prior) than described in the literature. Means for gestations age, birth weight, and lengthare 38.11 weeks, 2,789.34 g and 48.45 cm, respectively. Long-term survivors presented with syndromerelated physical characteristics (e.g., low-set ears, cleft lip and palate) and medical conditions (e.g., ventricular septal defect (VSD), feeding difficulties). We conclude that data indicate longer survival and a range in birth information (gestational age, birth weight, and length) along with presence of common presenting physical characteristics and medical conditions of long-term survivors with full t13.

Research Letter Patau Syndrome With a Long Survival (146 Months): A Clinical Report and Review of Literature

American Journal of Medical Genetics 140A:92 – 93 (2006) 

Trisomy 13 is a clinically severe condition first described by Patau in 1960 [Smith et al., 1960]. The frequency of this syndrome is 1:3,000 live births [Tunca et al., 2001]. It is the third most frequent trisomy among live births [Phatak et al., 2004] after trisomy 21 (Down syndrome) and trisomy 18 (Edwards syndrome). Eighty-five percent of liveborns do not survive beyond 1 year of life, and most die before the age of 6 months [Duarte et al., 2004]. Trisomy 13 is characterized by multiple malformations of the cardiac, central nervous, and urogenital systems [Phatak et al., 2004]. There have only been five cases of patients with trisomy 13 previously reported, who had survived past the first decade [Redheendran et al., 1981; Singh, 1990; Zoll et al., 1993; Tunca et al., 2001]. In this report, we present a newborn with trisomy 13, the fourth longest described in the literature and the longest survival (146 months) reported in Greece. (Keep reading it…)
