PKR, an interferon (IFN)-inducible protein kinase activated by double-stranded RNA, inhibits translation by phosphorylating the initiation factor eIF2alpha chain. We show that human IFN-gamma mRNA uses local activation of PKR in the cell to control its own translation yield. IFN-gamma mRNA activates PKR through a pseudoknot in its 5' untranslated region.(More)
The Samaritan community is a small, isolated, and highly endogamous group numbering some 650 members who have maintained extensive genealogical records for the past 13-15 generations. We performed mutation detection experiments on mitochondrial DNAs and Y chromosomes from confirmed maternal and paternal lineages to estimate mutation rates in these two(More)
Usher syndrome types I (USH1A-USH1E) are a group of autosomal recessive diseases characterized by profound congenital hearing loss, vestibular areflexia, and progressive visual loss due to retinitis pigmentosa. The human myosin VIIA gene, located on 11q14, has been shown to be responsible for Usher syndrome type 1B (USH1B). Haplotypes were constructed in 28(More)
We characterized microsatellite marker haplotypes and identified mutations in members of 19 ethnically diverse Israeli families affected by Wilson disease (WD). Eighteen unique haplotypes were derived from allelic combinations for four marker loci spanning the WD gene, ATP7B, at chromosome 13q14.3: D13S133, D13S296, D13S301 and D13S295. Most of these(More)
