Hypophosphatasia (/ ˌ h aɪ p oʊ ˈ f ɒ s f eɪ t ˌ eɪ ʒ ə /; also called deficiency of alkaline phosphatase, phosphoethanolaminuria, [5] or Rathbun's syndrome; [1] sometimes abbreviated HPP [6]) is a rare, and sometimes fatal, inherited [7] metabolic bone disease. [8]
The enzyme alkaline phosphatase (ALP, alkaline phenyl phosphatase) is a phosphatase with the physiological role of dephosphorylating compounds. The enzyme is found across a multitude of organisms, prokaryotes and eukaryotes alike, with the same general function, but in different structural forms suitable to the environment they function in. Alkaline phosphatase is found in the periplasmic ...
Of note, alkaline phosphatase and bilirubin are usually normal. Autoimmune hepatitis may overlap with other autoimmune conditions, mainly type 1 diabetes mellitus, ulcerative colitis, lupus, celiac disease, vasculitis, and autoimmune thyroiditis. [5]
Alkaline phosphatase levels are relatively low in those with Wilson's-related acute liver failure. [20] If neurological symptoms are seen, magnetic resonance imaging of the brain is usually performed; this shows hyperintensities in the part of the brain called the basal ganglia in the T2 setting. [14]
Laboratory findings include low-normal serum calcium, moderately low serum phosphate, elevated serum alkaline phosphatase, and low serum 1,25 dihydroxy-vitamin D levels, hyperphosphaturia, and no evidence of hyperparathyroidism. [8] Hypophosphatemia decreases 2,3-bisphosphoglycerate (2,3-BPG) causing a left shift in the oxyhemoglobin curve.
Primary biliary cholangitis (PBC), previously known as primary biliary cirrhosis, is an autoimmune disease of the liver. [1] [2] [3] It results from a slow, progressive destruction of the small bile ducts of the liver, causing bile and other toxins to build up in the liver, a condition called cholestasis.
Mutations in the ALPL gene lead to varying low activity of the enzyme tissue-nonspecific alkaline phosphatase (TNSALP or TNAP) resulting in hypophosphatasia (HPP). [21] There are different clinical forms of HPP which can be inherited by an autosomal recessive trait or autosomal dominant trait, [18] the former causing more severe forms of the ...
A serum alkaline phosphatase less than 1.5 times the upper limit of normal has been associated with better outcomes, but its use in predicting long-term outcomes is unclear. [1] An IgA isotype autoantibody to the pancreatic GP2 protein (anti-GP2 IgA antibody) is the first verified prognostic biomarker in PSC. [35]
