Minisatellite isoallelism, i.e. the occurrence of minisatellite alleles with different internal sequence composition but indistinguishable length, is a common limitation of minisatellite allele length analysis. Internal sequence variation can be used to distinguish such isoalleles, provided that detailed sequence knowledge of its basis is available. We now show that minisatellite isoalleles can...

Hemophilia B is an X-linked recessive bleeding disorder caused by heterogeneous mutations in factor IX gene. In about one-third of cases it arises by a new mutation in germ-line cells. In this study carrier testing was performed for females of a family with only one affected individual by single strand conformation polymorphism (SSCP). Results indicated that the SSCP band shift in the propositu...

Hereditary hemochromatosis (HHC) represents an autosomal recessive disease in which increased iron absorption causes iron overload and irreversible tissue damage. The recently detected association between two point mutations in the HFE gene on chromosome 6p and HHC has made it possible to screen for the disease before the onset of irreversible tissue damage. Conventional genetic testing is base...

Genotypes of Iranian Zel sheep for Calpastatin(CAST) locus were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) methods and for Calpain(CAPN) locus by PCR-SSCP. Blood samples were collected from 200 purebred Zel sheep of Zel Breeding Station located in Golestan province i...

Tkáãiková a. , M. R. , Bhide I . Mikula: Asymmetric PCR-SSCP: a Useful Tool for Detection of OLA-DRB1(MHC class II) Gene Polymorphism in Slovak Improved Valachian Sheep. Acta Vet. Brno 2005, 74: 275-278. Detection of OLA-DBR1 (exon 2) gene polymorphism is presented in the paper. Rapid and inexpensive polymorphism detection method, namely, single stranded conformation polymorphism (SSCP) was ass...

Our purpose was to search for mutations in the apolipoprotein E (apoE) gene and to evaluate the role of apoE polymorphisms in the occurrence of autosomal dominant retinitis pigmentosa (ADRP). The ApoE gene coding sequence was analyzed in 51 unrelated patients affected with ADRP. A screening for mutations by SSCP and an analysis of the apoE polymorphisms were performed using PCR and restriction ...
