Introduction: Premature ovarian failure (POF) is defined as a heterogeneous disease leading to amenorrhea and ovarian failure before the age of 40 years. It is found in 1-3% of women of reproductive age, with some negative consequences such as cardiovascular disease, osteoporosis and sexual dysfunction. Triple X syndrome is characterized by POF with primary or secondary amenorrhea, tall stature, large feet. Girls with triple X syndrome show accelerated growth ...

The epidemic spread of obesity in children has triggered the commitment of scientific research, which has allowed us to understand its genetic basis; the different forms of genetic obesity share common clinical aspects, making it difficult to achieve a molecular diagnosis based only on our clinical suspicion. We report a female patient presented with neonatal hypotonia, hyperphagia and early onset excessive weight gain, strabismus and high hypermetropia. Regarding her neurodev...

Background: Turner syndrome, a condition that affects only girls and women, result when the X chromosome is missing or partially missing. Ornithine transcarbamylase (OTC) deficiency, the most common inherited urea cycle disorder, is transmitted as a partially dominant X-linked trait. The OTC gene maps to Xp21.1 and spans approximately 73 kb, containing 10 exons and 9 introns. OTC deficiency is diagnosed using a combination of clinical findings and biochemical testing, while co...

Background: Hereditary Nephrogenic Diabetes Insipidus (HNDI) is an uncommon disorder due to a resistance to anti diuretic hormone (ADH) leading to a reduced urinary concentrating ability. The X-linked form is fully expressed in hemizygous male patients, but diabetes insipidus may also present in heterozygous females where it must be distinguished from autosomal and other secondary causes.Objective and hypotheses: We report a mother and daughter with HNDI...

Background: MEHMO (microcephaly, epilepsy, hypogenitalism, mental retardation, obesity) is a rare disorder with X-linked inheritance. Only three families with this disorder were described previously, with the linkage to a region on X chromosome. No specific gene has been identified so far.Aims and objectives: The aim was to identify the genetic etiology in two unrelated Slovak male probands (4.5 and 1.5 years old respectively) with the clinical diagnosis...

Objective: To analyse chromosomal abnormalities of the patients who were referred for the screening of short stature and delayed puberty and to verify the association between karyotype and phenotype in confirmed Turner Syndrome (TS) patients.Study Design: Descriptive study. Place and Duration of Study: Department of Pediatric Endocrinology and Diabetes Unit-II, National Institute of Child Health, Karachi, from January 20...

Introduction: Physiological pubertal gynecomastia is common in adolescents aged 13-14 years. Most physiological pubertal gynecomastia regresses spontaneously within 1-2 years. In studies: If it lasts more than 2 years, if prepubertal has started, endocrine evaluation is recommended. Sex differentiation disorders or genital abnormalities such as increased aromatase activity, adrenal/testicular neoplasia, partial androgen insensitivity syndrome and Klinefelter s...

Background: Turner syndrome (TS) is caused by complete or partial of the second sex chromosome and characterized bygrowth failure, primary ovarian failure, the constellation of the lymphedema sequence, characteristic facial features, left-sided cardiac anomalies, renal anomaly, and skeletal anomalies. Among all of the associated traits, cardiovascular abnormalities are common in TS and an important cause of early mortality. Hence, our aim is to investigate the...

Background: Turner syndrome (TS) is caused by a total or partial loss of one X chromosome. Typical features include short stature and primary amenorrhoea. In addition, decreasing trabecular bone mineral density (BMD) and increasing cortical BMD during puberty has been reported at the radius. As chromosomal aberration remains a probable cause of bone changes in TS, we aimed to elucidate whether the karyotype differs among the tissues originating from the three ...

Introduction: Klinefelter syndrome (KS) describes the phenotype of the most common sex chromosome abnormality in humans. About 80% of KS patients have 47,XXY karyotype, while rest of the patients can have mosaicism or other numeric or structural sex chromosome abnormalities. Tall stature is one of the hallmarks of KS and it is thought to be due to supernumerary X chromosome leading to SHOX gene overdosage. Deletion of SHOX gene, on the contrary, has been r...
