Background:
McCune Albright syndrome is rare with an estimated prevalence of 1 in 100,000 to 1 in 1,000,000 persons. The classical clinical triad consists of fibrous dysplasia of the bone, café-au-lait skin spots and precocious puberty. However, in rare cases, there may be primary hypogonadism and amenorrhea.
Case Presentation:
An eighteen-year-old female presented with amenorrhea. She had a short stature, round face, thick neck, and short fourth metacarpals and metatarsals. The secondary sexual characters were absent. Serum calcium, phosphorus and parathyroid concentrations were normal, but gonadotropin hormones were very low. X-ray examination revealed short fourth and fifth metacarpals, short left metatarsal, and short fibula.
Conclusion:
These local bony abnormalities along with the biochemical findings helped us to diagnose this case as an unusual presentation of primary hypogonadism with features of McCune Albright's syndrome where there was amenorrhea rather than preocious puberty.

Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...
Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
