Amelogenin sex determination in Merseyside

A commonly used PCR primer set first published by Sullivan et al. Hydrolysis not only causes short products, but also induces postmortem DNA modifications, called miscoding lesions. Among them, the amelogenin sex test is the most widely used in forensic practice and anthropological studies.

Teeth are one of the most resistant structures in the human body that resist decomposition hence making them prime choice for extracting DNA for identification of individuals.

Sex determination is a part of forensic odontology and an en essential priority when traditional identification of the deceased becomes impossible due to certain mishaps, including natural calamities, acts of war and terrorism or criminal cases of homicide and mutilation of bodies.

BB was responsible for funding, supervision of the research project, manuscript writing and editing as well as scientific correspondence. Y p Most commercial STR kits utilize the Sullivan et al. Clin Chim Acta. Most likely reason for the double phenotypic expression observed in vivo could be a reduction in the rate of hydrolysis of amelogenin and subsequent mineralization patterns.

External link. There are three schools of thought about exhibition of varied isoforms by amelogenin: first is the presence of two distinct sets of genes located in both the sex chromosomes, second is the production of numerous amelogenin mRNAs by alternative splicing and lastly they are proteolytic processed after secretion.

Until now, all major enamel matrix proteins and proteinases have already been cloned, characterized and their recent involvement in many cases of amelogenesis imperfecta has strengthened their foothold in the process of amelogenin sex determination in Merseyside development.

The malformed enamel in such cases show the presence of less inorganic and a higher organic content as compared to normal enamel. These methods are quite sensitive amplifiable from trace samples due to the multiplicity, but it is impossible to tell whether the template DNA is from a female or whether the analysis has ended in failure when no fragment is amplified by PCR.
