AIM: The objective of this study was to correlate the genotype, of female patients, withshort stature and primary amenorrhea. MATERIALS AND METHODS: One hundred and forty-six subjects were recruited during 2005-2012. Microscopic and automated karyotyping analyses were done by using chromosomes isolated from the lymphocytes using Giemsa banding (GTG) to identify chromosome abnormalities. RESULTS: A total of 146 clinically suspected Turner syndrome (TS) subjects were recruited for the study, of which, 61 patients were identified to have chromosome abnormalities. The chromosomal abnormalities detected were as follows: Monosomy X (n = 19, 13.01%), triple X syndrome (n = 4, 2.7%), mosaic TS (n = 12, 8.21%), XY gonadal dysgenesis (n = 13, 8.9%), and structural abnormalities including X chromosome (n = 15, 10.27%) and one patient each with autosomal changes involving 9qh inversion and translocation of chromosomes 12 and 14. CONCLUSION: Karyotype abnormalities accounting for 46% in this study emphasize the need for karyotype testing in cases of short stature with primary amenorrhea.

    Introduction: Turner syndrome is characterized by the absence, total or partial, of one X chromosome in females, being one of the most frequent chromosomal abnormalities. Diagnosis is made by karyotype. Turner syndrome manifestations include primary hypogonadism, before or after puberty (gonadal...

    Pterigium colli is a clinical finding that may be seen in Turner, Noonan and Klippel-Feil syndromes. The extracervical skin extending from the mastoid processes to the acromion constitutes curtains which may be bilateral and asymmetric, and the name of "flail neck" originates from this view. The...

    Ullrich-Turner syndrome (UTS) is a common chromosomal abnormality caused by partial or complete X chromosome monosomy. One half of the patients have a 45,X karyotype, whereas the remaining patients display other X chromosome anomalies. In 6% to 11% of UTS, a normal or partly deleted Y chromosome...

    Background. Mixed gonadal dysgenesis is a disorder of sex development associated with a numerical or sex chromosome abnormality. There is no association between the degree of mosaicism and the phenotype. Case report. An 11 years old girl was admitted for excessive weight [BMI: 31.55 kg/m² (+...

    The 47, XXX karyotype (triple X) has a frequency of 1 in 1000 female newborns. However, this karyotype is not usually suspected at birth or childhood. Female patients with a sex chromosome abnormality may be fertile. In patients with a 47, XXX cell line there appears to be an increased risk of a...
