(1966) suggested that the expression "Turner's phenotype" should be used to indicate the presence of sufficient Turner stigmata to arouse the clinical suspicion of Turner's syndrome but that unless dwarfism and streak gonads are con-firmed the term should be suitably qualified.

Girls with Turner syndrome usually present with primary amenorrhea or delayed puberty secondary to premature ovarian failure. Serum FSH and AMH should be measured at around 10 to 11 years of age. Serum AMH can help predict ovarian function, and patients with detectable levels are likely to experience spontaneous puberty. [14]. The distinctive facial features consist of a broad forehead, hypertelorism, down-slanting palpebral fissures, a high-arched palate, and low-set, posteriorly rotated ears.

Turner syndrome is a congenital condition, meaning it's something a person is born with. Each of us is born with two chromosomes. If you're female, you were born with two X chromosomes. If you're a male, you are born with one X and one Y chromosome. Turner Syndrome occurs when one of the X chromosomes is missing, either partially or completely.

BACKGROUND Turner syndrome is characterised by a 45,X karyotype and a variety of skeletal, lymphoedemic, and gonadal anomalies.

An Overview. Turner Syndrome and Klinefelter Syndrome are genetic disorders, caused by the variations in the number of sex chromosomes. The Turner syndrome is mainly caused in 1 out of 2000 live births of a female baby. This syndrome is mainly caused due to the partial or complete absence of one X or sex chromosomes.

Turner syndrome can be defined as loss or abnormality of the second X chromosome in at least one cell line in a phenotypic female. The condition occurs in approximately 1 in every 2000 live female births,[1][1] so that in the UK the prevalence for any year of life is in the region of 200 girls. The condition is much more common in utero, it being estimated that 1–2% of all conceptuses.

Turner syndrome (TS) are attributed to X-chromo­ some genomic imprinting. To investigate the possible contribution of imprinting to the physical features of the TS phenotype in live-born individuals, we geno­ typed the single normal X-chromosome in subjects with TS who all underwent a comprehensive evalua­. Turner syndrome (TS) is a chromosomal disorder that is caused by a missing or structurally abnormal second sex chromosome. Subjects with TS are at an increased risk of developing intrauterine growth retardation, low birth weight, short stature, congenital heart diseases, infertility, obesity, dyslipidemia, hypertension, insulin resistance, type 2 diabetes.

This abnormality can cause medical problems such as a webbed neck, low-set ears, and heart or kidney defects.

People with Noonan syndrome have distinctive facial features such as a deep groove in the area between the nose and. Oftentimes, the PCP suspects a genetic etiology of an unusual phenotype, such as pinna placement or other unusual ear configurations, webbed neck with low posterior hairline, wide-spaced nipples, or short stature among other presentations.
