Publikováno v: Clinical Genetics. 90:437-444

Mutations in SPATA5 have recently been shown to result in a phenotype of microcephaly, intellectual disability, seizures, and hearing loss in childhood. Our aim in this report is to delineate the SPATA5 syndrome as a clinical entity, including the fa

Three Japanese patients with 3p13 microdeletions involving FOXP1

Autor: Tetsuya Okazaki, Keiko Yamamoto-Shimojima, Wataru Matsumura, Nobuhiko Okamoto, Toshiyuki Yamamoto

Publikováno v: Braindevelopment. 41(3)

Background FOXP1 is known as the gene responsible for neurodevelopmental delay associated with language impairment. Broad clinical findings also include feeding difficulty, muscular hypotonia, and distinctive features. These findings are common betwe

Changes in the GHG emission intensity in EU-15: Lessons from a decomposition analysis

Autor: Subhes C. Bhattacharyya, Wataru Matsumura

This paper analyses the reduction in greenhouse gas emissions in 15 countries of the European Union between 1990 and 2007 to find out the contribution of different countries. Using the log-mean Divisia index decomposition approach, it identifies the
