All of the processes of embryo development are described by the term embryogenesis. The embryo is called a fetus after the completion of this stage of development. The stage of prenatal development that occurs from the end of the embryonic period until birth is called the fetal period.
New genetic cause of osteoporosis found, rare gene identified. By: Bel Marra Health | Osteoporosis | Tuesday, September 15, 2015 - 17:30 PM. A rare gene â the EN1 gene â has been identified as a potential osteoporosis cause by researchers at McGill University.With the use of extensive genetic data from the UK10K project, the research team uncovered that a variant of the EN1 gene has a large effect on bone mineral density (BMD).ew genetic cause of osteoporosis found, rare gene identified.

Osteoporosis has 3 causes: 1) excess parathyroid hormone, 2) advanced age, and 3) lack of estrogen in older females. This page is primarily about cause number one--osteoporosis due to parathyroid disease...although you can see that if you are a female over the age of 50 you are getting a triple-whammy.
