Hypothyroidism and sex chromosomes.
The observation of Campbell and Price in 1979 that their Unit had diagnosed four subjects with both Klinefelter's syndrome and congenital hypothyroidism raised the suspicion of an association between the two conditions. This, and the published reports of an XX male, five XXY males, and one mosaic XY/XXY with congenital or acquired forms of hypothyroidism, together with the higher incidence in w...
متن کاملLG24 and sex chromosomes
The grass carp (Ctenopharyngodon idella) is one of the most important freshwater fish species in China and the world; grass carp production accounts for about 16% of the world’s total freshwater aquaculture [1]. In 2015, Wang et al. performed whole-genome sequencing and de novo assembly for a female (0.9 Gb) and male grass carp (1.07 Gb) by using the shotgun sequencing strategy [2]. Based on th...
متن کاملSex chromosomes, sex determination, and sex-linked sequences in Microtidae.
The Arvicolidae is a widely distributed rodent group with several interesting characteristics in their sex chromosomes. Here, we summarize the actual knowledge of some of these characteristics. This mammalian group has species with abnormal sex determination systems. In fact, some species present the same karyotype in both males and females, with total absence of a Y chromosome, and hence of SR...
متن کاملMetabolic impact of sex chromosomes
Obesity and associated metabolic diseases are sexually dimorphic. To provide better diagnosis and treatment for both sexes, it is of interest to identify the factors that underlie male/female differences in obesity. Traditionally, sexual dimorphism has been attributed to effects of gonadal hormones, which influence numerous metabolic processes. However, the XX/XY sex chromosome complement is an...
متن کاملPlant Evolution: Modern Sex Chromosomes
The first detailed map has been produced of a plant chromosome carrying sex-determining genes. The new data show that, in papaya, these genes lie in a quite extensive non-recombining region. This region is nevertheless a small part of the papaya genome compared with other male-specific genome regions, such as mammalian Y chromosomes.
