"Advances in Genetics Research" presents original research results on the leading edge of genetics discovery. Each article has been carefully selected in an attempt to present substantial research results across a broad spectrum. In this continuing series compilation, the authors present and discuss mitochondrial gene diversity of the mega-herbivorous species of the genus Tapirus (tapiridae, perissodactyla) in South America and some insights on their genetics conservation, systematics and the pleistocene influence on their genetic characteristics; strategies for gene prospecting of plants in response to drought and salinity; clinical evidence and the genetic effects of traditional Chinese medicine for the management of proteinuria in patients with diabetic nephropathy; biochemistry and genetics of ansamycin antibiotics; BRCA gene mutations mediate particularly high TNBC risk by defective estrogen signaling; genotype-phenotype relationships in language processes in Rett syndrome; Marfan syndrome; Marfan syndrome and periodontitis; combined pectus correction and aortic valve sparing root replacement in Marfan patients; severe periodontitis in Marfan syndrome; and preimplantation genetic diagnosis for Marfan syndrome.
