Tryptase alpha/beta 1

From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history

Tryptase alpha/beta 1 or TPSAB1 is a protein-encoding gene for tryptase.[1]

Function[edit | edit source]

Hereditary alpha tryptasemia syndrome[edit | edit source]

Extra copies of the TPSAB1 gene is known as familial hypertryptasemia (FHT) or hereditary alpha tryptasemia (H⍺T or HAT) and is one of several possible causes for increased tryptase production.[2] HAT is common and often does not cause illness.[2]

Hereditary alpha tryptasemia syndrome (HATS) is a recently discovered multi-systemic illness involving an increased number of TPSAB1 genes with a cluster of symptoms similar to those found in MCAS.

Other symptoms and diseases[edit | edit source]

The TPSAB1 has also been implicated in pruritus, medically unexplained (functional) gastrointestinal symptoms and in.[3][2]
