ABSTRACT
@#A 31-year-old lady with normal physical characteristics was found to have persistent high FSH and LH and was suspected possible premature ovarian failure after reported to have not normal menstrual cycle. Leucocytes were collected from patient’s fresh peripheral blood sample and Giemsa banding (G-banding) was done. All metaphases were captured and analysed using Cytovision software 4.5 and the final analysis show 47,XXX

@#Advanced parental age is a risk factor for chromosomal abnormalities in their offspring. Trisomy X or Triple X syndrome has previously been reported with advanced maternal age. Here we report two (2) cases of Trisomy X with paternal age as risk factor. Generally, Trisomy X individuals show variable physical and psychological manifestations. However, both cases reported here have advanced paternal age as a risk factor; 55 years old (46 years old at conception) for Case 1 with patient having right eye squint, beaked nose, Posterior Misalignment Type Ventricular Septal Defect (PMVSD) and small Patent Ductus Arteriosus (PDA) with failure to thrive and 49 years old (45 years old at conception) for Case 2 with speech delay and protruding tongue. In view of that, advanced paternal age could possibly contribute the accumulation of de novo mutations in germ line mosaicism.

El síndrome 47, XXX se debe a un cromosoma extra del par sexual; su incidencia es de 1 en 1000 recién nacidas vivas. Sin embargo, este síndrome no suele sospecharse al nacimiento ni en la infancia. Muchas de estas pacientes son diagnosticadas durante la edad adulta por falla ovárica precoz o esterilidad, debido a la falta de características clínicas específicas .Este trabajo describe cuatro casos de pacientes 47, XXX y su variabilidad fenotípica.
The 47, XXX karyotype has a frequency of 1 in 1000 female newborns. However, this karyotype is not usually suspected at birth or childhood. These patients are usually diagnosed duringadulthood when they develop premature ovarian failure or infertility, because the early phenotype doesn't have anyspecific features. The study describes four cases and the clinical variability of the 47, XXX karyotype.

The live birth of a triploidy infant is a very rare event and death usually occurs within the first hours of life. Triploid cases with a survival of more than two months are infrequent. We report on an infant with a 69,XXX chromosome constitution who survived 164 days. Chromosomal analysis demonstrated a 69,XXX karyotype with no evidence of mosaicism. This is the longest survival reported for this condition to date in Greece and the fourth longest worldwide. The infant was admitted to our clinic several times due to respiratory problems, and supplementary oxygen was required. The improved survival of our case was possibly due to better management of respiratory illness and prematurity, and these are essential factors that physicians should consider carefully with such rare cases.
