Choroideremia (/ k ɒ ˌ r ɔɪ d ɪ ˈ r iː m i ə /; CHM) is a rare, X-linked recessive form of hereditary retinal degeneration that affects roughly 1 in 50,000 males. The disease causes a gradual loss of vision, starting with childhood night blindness, followed by peripheral vision loss and progressing to loss of central vision later in life.
Osteopenia, known as "low bone mass" or "low bone density", is a condition in which bone mineral density is low. [1] Because their bones are weaker, people with osteopenia may have a higher risk of fractures, and some people may go on to develop osteoporosis. [2] In 2010, 43 million older adults in the US had osteopenia. [3]
Dent's disease (or Dent disease) is a rare X-linked recessive inherited condition that affects the proximal renal tubules [1] of the kidney.It is one cause of Fanconi syndrome, and is characterized by tubular proteinuria, excess calcium in the urine, formation of calcium kidney stones, nephrocalcinosis, and chronic kidney failure.
A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.

Diagnosis is typically based on medical imaging, including plain X-rays, and symptoms. In severe OI, signs on medical imaging include abnormalities in all extremities and in the spine. [ 97 ] As X-rays are often insensitive to the comparatively smaller bone density loss associated with type I OI, DEXA scans may be needed.
