This article is about the subtype of pseudohypoparathyroidism known as Albright's hereditary osteodystrophy. For the genetically-related condition, see McCune–Albright syndrome.
Medical condition
Albright's hereditary osteodystrophy
Albright's hereditary osteodystrophy has an autosomal dominant pattern of inheritance
Individuals with Albright hereditary osteodystrophy exhibit short stature, characteristically shortened fourth and fifth metacarpals, rounded facies, and often mild intellectual deficiency.[5]
The mechanism of this condition is due to Gs signaling decrease in hormones having to do with signal transduction which is when a signal from outside cell causes change within the cell (in function). Renal tubule cells only express maternal alleles (variant form of a gene).[6][7][8]
Diagnosis
The diagnosis of Albright's hereditary osteodystrophy is based on the following exams below:[9]
Treatment consists of maintaining normal levels of calcium, phosphorus, and vitamin D. Phosphate binders, supplementary calcium and vitamin D will be used as required.[3]
History
The disorder bears the name of Fuller Albright, who characterized it in 1942.[12] He was also responsible for naming it "Sebright bantam syndrome," after the Sebright bantam chicken, which demonstrates an analogous hormone insensitivity. Much less commonly, the term Martin-Albright syndrome is used, this refers to Eric Martin.[13]
