Clinical-pathological correlations in three patients with fibrodysplasia ossificans progressiva.

Objective: Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare genetic disorder in which heterotopic bone forms in the soft tissues. This often occurs in response to injury or inflammation, leading to joint immobilization and significant disability. There are currently no definitive treatment options for this devastating disease.

Natural epigenetic variation in the female great roundleaf bat (Hipposideros armiger) populations.

Epigenetic modifications are considered to have an important role in evolution. DNA methylation is one of the best studied epigenetic mechanisms and methylation variability is crucial for promoting phenotypic diversification of organisms in response to environmental variation. A critical first step in the assessment of the potential role of epigenetic variation in evolution is the identification of DNA methylation polymorphisms and their relationship with genetic variations in natural populations.
