Introduction: Klinefelter syndrome (KS) is a form of aneuploidy resulting from 2 or more X chromosomes in a male. The most common karyotype is 47, XXY. KS affects physical and intellectual development to varying degrees, commonly causing hypo-development of secondary sexual characters and high stature.Case Report: JLV, male, 3 year 1 month age, the first child of a young non-consanguineous couple, was referred to the ped...

Background: Growth is a complex process influenced by several genetic factors both pre and postnatal, in which 80% of the height variation is explained by genetic factors. Nevertheless, the standard medical evaluation of short stature (SS) relies upon physical examination and laboratory parameters and identifies a pathological cause of SS in 1–40% of individuals. Recent advances in genetic diagnosis are revolutionizing the clinician’s ability to obtain a molecular di...

Background: In total of 48,XXYY Syndrome occurs in 1:20.000–1:50.000 male births. It used to be considered as a variant of Klinefelter syndrome, but now it is considered as a distinct clinical and genetic entity with increased risks for congenital malformations, additional medical problems and more complex psychological and neurodevelopmental involvement. 48,XXYY Syndrome results from the fertilization of a normal female oocyte (Xm), with an aneuploid sperm (XpYpYp) produ...

Background and Aims: Turner Syndrome (TS), 45X0, is the most common chromosomal pathology affecting females, occurring in 1:2500 to 1:5000 female infants. The typical phenotype includes short stature, gonadal dysgenesis leading to sexual infantilism, low-set ears, low rear hairlin, mamary hypertelorism, neck webbing, gothic palate, irregular rotation of the elbows, shield chest, shortening of the 4th metacarpal, low hairline, shortening of lower extremities, renal disorders a...

Introduction: Growth is a complex process influenced by several genetic factors both pre and postnatal, in which 80% of the height variation is explained by genetic factors. Nevertheless, the standard medical evaluation of short stature (SS) relies upon physical examination and laboratory parameters and identifies a pathological cause of SS in 1–40% of individuals. Rearrangements affecting chromosome 15 are rare and affected patients show a variety of nonspecific features...
