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 ...
Prenatal diagnosis of fetal trisomies is usually performed by cytogenetic analysis on amniotic fluid. This requires lengthy laboratory procedures and high costs, and is unsuitable for large scale screening of pregnant women. An alternative method, which is both rapid and inexpensive and suitable for diagnosing trisomies even from single fetal cells, is the fluorescent polymerase chain reaction ...
Tandem repeats are short DNA sequences that are repeated head-to-tail with a propensity to be variable. They constitute a significant proportion of the human genome, also occurring within coding and regulatory regions. Variation in these repeats can alter the function and/or expression of genes allowing organisms to swiftly adapt to novel environments. Importantly, some repeat expansions have a...
The Wichí people from Chaco Province inhabit the region called Impenetrable Chaqueño, where the climatic conditions are extreme. Besides scarce communication with the main urban centers, the cultural patterns of the Wichí cause these communities to live in certain degree of isolation. The effect of this situation is an increased genetic differentiation from other populations, as it was observed...
