Progressive Cone-Rod Dystrophy and RPE Dysfunction in Mice.

Mutations in the mouse microphthalmia-associated transcription factor () gene affect retinal pigment epithelium (RPE) differentiation and development and can lead to hypopigmentation, microphthalmia, deafness, and blindness. For instance, an association has been established between loss-of-function mutations in the mouse gene and a variety of human retinal diseases, including Waardenburg type 2 and Tietz syndromes. Although there is evidence showing that mice with the homozygous mutation manifest microphthalmia and osteopetrosis, there are limited or no data on the effects of the heterozygous condition in the eye.

Loss-of-Function Variants in the Tumor-Suppressor Gene Confer Increased Cancer Risk.

The success of genome-wide association studies (GWAS) in identifying common, low-penetrance variant-cancer associations for the past decade is undisputed. However, discovering additional high-penetrance cancer mutations in unknown cancer predisposing genes requires detection of variant-cancer association of ultra-rare coding variants. Consequently, large-scale next-generation sequence data with associated phenotype information are needed.

Genome-wide association identifies seven loci for pelvic organ prolapse in Iceland and the UK Biobank.

Pelvic organ prolapse (POP) is a downward descent of one or more of the pelvic organs, resulting in a protrusion of the vaginal wall and/or uterus. We performed a genome-wide association study of POP using data from Iceland and the UK Biobank, a total of 15,010 cases with hospital-based diagnosis code and 340,734 female controls, and found eight sequence variants at seven loci associating with POP (P < 5 × 10); seven common (minor allele frequency >5%) and one with minor allele frequency of 4.87%.

Common and Rare Sequence Variants Influencing Tumor Biomarkers in Blood.

Background: Alpha-fetoprotein (AFP), cancer antigens 15.3, 19.9, and 125, carcinoembryonic antigen, and alkaline phosphatase (ALP) are widely measured in attempts to detect cancer and to monitor treatment response.

[Health and survival in Icelandic nursing homes 2003 - 2014, before and after the setting of stricter criteria for nursing home admission in December 2007].

Introduction: Many factors influence the nursing needs and survival of nursing home residents, including the admission criteria. The aim of the study was to compare health, survival and predictors for one- and two-year survival of people entering Icelandic nursing homes between 2003-2007 and 2008-2014.

Material And Methods: Retrospective, descriptive, comparative study.
