The aim of the study was to determine sex fetus in gene expression data lacking this information using Y-linked genes, and elucidate difference between sex-chromosomal-linked placental samples with XX XY genotypes during pregnacy. We have detected 27 differentially expressed sex-chromosomes-linked genes. shown that, most cases, genes from X-chromosomes pregnancy carrying baby girls is higher th...

We study the fractional populations in chromosome inherited diseases. The governing equations for the fractional populations are found and solved in the presence of mutation and selection. The physical fixed points obtained are used to discuss the cases of color blindness and hemophilia. 87.10.+e, 42.62.Be Typeset using REVTEX

An unusual form of hereditary spastic paraplegia is described. Affected females have a late-onset slowly progressive spastic paraparesis. Affected males show oligophrenia with a rapidly progressive spastic quadriplegia. The mode of inheritance is consistent with sex-linkage, with partial manifestation in female carriers.

From January 1 to July 31, 2000, 148 cases of Shigella infection were reported in New South Wales, Australia, compared with an annual average of 95 cases. Of reported cases, 83% were confirmed as Shigella sonnei biotype G infections; 80% were in homosexual men. Visiting a sex venue in the 2 weeks before onset of illness was the only factor significantly associated with shigellosis.

phenylketonuria (pku) is one of the most common metabolic inborn diseases caused by mutations in the phenylalanine hydroxylase (pah) gene. this gene is linked to a variable number of tandem repeats (vntr) region which is a polymorphic marker that facilitates the implementation of prenatal diagnosis and carrier screening. in this study, vntr with 13 repeats that has not been reported previously ...
