Background: Recurrent hydatidiform moles (RHMs) are an unusual pregnancy with at least two molar gestations that are associated with abnormal proliferation of trophoblastic tissue and a failure in the embryonic tissues development. Three maternal-effect genes, including NLRP7, KHDC3L, and PADI6 have been identified as the cause of RHMs. The present study aimed to understand the association of a...
BACKGROUND Introducing point mutations into bacterial chromosomes is important for further progress in studies relying on functional genomics, systems- and synthetic biology, and for metabolic engineering. For many investigations, chromosomal systems are required rather than artificial plasmid based systems. RESULTS Here we describe the introduction of a single point mutation into the Escheri...
We cloned and sequenced the cDNAs for R-type pyruvate kinase (R-PK) from three homozygous PK patients. A point mutation (1151ACG to ATG) identified in the R-PK cDNA of PK Nagasaki was identical with that previously identified in an unrelated family, PK Tokyo. The mutation has also been identified in the PK L gene of a Lebanese family, PK Beirut, by Neubauer et al (Blood 77:1871, 1991). These re...
