background: translocations involving x chromosome and an autosome are rather rare due to associated infertility in men and subfertility in women. x chromosome translocations are frequently associated with primary or secondary amenorrhea. in this report, a case of primary amenorrhea with a de novo balanced reciprocal translocation was presented between chromosomes x and 1. case presentation: a 2...

AbstractChromosomal translocations constitute one of the most important, yet uncommon, causes of primary amenorrhea and gonadal dysgenesis. Although X-autosome translocations are frequently associated with streak gonads and clinical features of the Turner syndrome, the majority of X-autosome carriers may present with a variable phenotype, developmental delay, and recognizable X-linked syndrome ...

introduction: x chromosome inactivation (xci) is a process during which one of the two x chromosomes in female human is silenced leading to equal gene expression with males who have only one x chromosome. here we have investigated xci ratio in females with opioid addiction to see whether xci skewness in women could be a risk factor for opioid addiction. methods: 30 adult females meeting dsm iv ...

turner syndrome is one of the most common cytogeneti disorders in human with an incidence of one case in about 2500 female live born children. most patients have sexual infantilism and pregnancy is rare. bahner reported the first case of a pregnant turner patients and then the pregnancy of such patients has not been considered impossible. 9 patients out of 243 turner patients referred to karimi...

the tribe sophoreae sensu polhill [9,10] is a large and diverse assemblage comprising the ancient and primitive ancestral stocks of papilionoideae. the most frequent chromosome basic numbers in this tribe are x = 11 and x = 9 but chromosome numbers range from x = 8-14 are also known. in this study chromosome numbers and karyotype variation of iranian members of tribe sophoreae are reported. ira...

Caryological studies were carried out on ten species of the genus Suaeda belonging to 27 samples of different populations in Iran. Important chromosome features including numbers, lengths, centromere locations and caryotypes were studied. All the species have basic chromosome numbers of x=9. Chromosome counts of S. acuminata (C.A.Mey.) Moq. (2n=18), S. aegyptiaca (Hasselq.) Zoh., (2n=l8)...

turner syndrome is one of the best known chromosome anomalies in human being, by an approximate incidence of 1/2500 female at birth. the cause is a chromosomal aberration, mainly with the karyotype 45, x. ninety six patients aged 6 to 26 years with short stature were studied for chromosomal anomalies. out of these 82 were phenotypically female and 14 phenotypically male. twenty seven showed abn...
