Maternal germ-line transmission of mutant mtDNAs from embryonic stem cell-derived chimeric mice

Sligh, James E., Levy, Shawn E., Waymire, Katrina G., Allard, Paulette, Dillehay, Dirck L., Nusinowitz, Steven, ...

We report a method for introducing mtDNA mutations into the mouse female germ line by means of embryonic stem (ES) cell cybrids. Mitochondria were recovered from the brain of a NZB mouse by fusion of...

A deletion in a photoreceptor-specific nuclear receptor mRNA causes retinal degeneration in the rd7 mouse

Akhmedov, Novrouz B., Piriev, Natik I., Chang, Bo, Rapoport, Ana Lia, Hawes, Norman L., Nishina, Patsy M., ...

The rd7 mouse, an animal model for hereditary retinal degeneration, has some characteristics similar to human flecked retinal disorders. Here we report the identification of a deletion in a...

Mutations in the crumbs homologue 1 (CRB1) gene cause a specific form of retinitis pigmentosa (RP) that is designated “RP12” and is characterized by a preserved para-arteriolar retinal pigment...

Remapping of the RP15 Locus for X-Linked Cone-Rod Degeneration to Xp11.4-p21.1, and Identification of a De Novo Insertion in the RPGR Exon ORF15

Mears, Alan J., Hiriyanna, Suja, Vervoort, Raf, Yashar, Beverly, Gieser, Linn, Fahrner, Stacey, ...

X-linked forms of retinitis pigmentosa (XLRP) are among the most severe, because of their early onset, often leading to significant vision loss before the 4th decade. Previously, the RP15 locus was...

Genetic Heterogeneity of Usher Syndrome: Analysis of 151 Families with Usher Type I

Astuto, Lisa M., Weston, Michael D., Carney, Carol A., Hoover, Denise M., Wagenaar, Mariette, ...

Usher syndrome type I is an autosomal recessive disorder marked by hearing loss, vestibular areflexia, and retinitis pigmentosa. Six Usher I genetic subtypes at loci USH1A–USH1F have been reported....
