Description:
Sialic acid acetylesterase (SIAE) is an enzyme that negatively regulates B lymphocyte antigen receptor signalling and is required for the maintenance of immunological tolerance in mice. Heterozygous loss-of-function germline rare variants and a homozygous defective polymorphic variant of SIAE were identified in 24/923 subjects of European origin with relatively common autoimmune disorders and in 2/648 controls of European origin. All heterozygous loss-of-function SIAE mutations tested were capable of functioning in a dominant negative manner. A homozygous secretion-defective polymorphic variant of SIAE was catalytically active, lacked the ability to function in a dominant negative manner, and was seen in eight autoimmune subjects but in no control subjects. The odds ratio for inheriting defective SIAE alleles was 8.6 in all autoimmune subjects, 8.3 in subjects with rheumatoid arthritis, and 7.9 in subjects with type I diabetes. Functionally defective SIAE rare and polymorphic variants represent a strong genetic link to susceptibility in relatively common human autoimmune disorders.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2900412/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2900412/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Surolia, Ira -- Pirnie, Stephan P -- Chellappa, Vasant -- Taylor, Kendra N -- Cariappa, Annaiah -- Moya, Jesse -- Liu, Haoyuan -- Bell, Daphne W -- Driscoll, David R -- Diederichs, Sven -- Haider, Khaleda -- Netravali, Ilka -- Le, Sheila -- Elia, Roberto -- Dow, Ethan -- Lee, Annette -- Freudenberg, Jan -- De Jager, Philip L -- Chretien, Yves -- Varki, Ajit -- MacDonald, Marcy E -- Gillis, Tammy -- Behrens, Timothy W -- Bloch, Donald -- Collier, Deborah -- Korzenik, Joshua -- Podolsky, Daniel K -- Hafler, David -- Murali, Mandakolathur -- Sands, Bruce -- Stone, John H -- Gregersen, Peter K -- Pillai, Shiv -- AI 064930/AI/NIAID NIH HHS/ -- AI 068759/AI/NIAID NIH HHS/ -- AI 076505/AI/NIAID NIH HHS/ -- AR 022263/AR/NIAMS NIH HHS/ -- AR 044422/AR/NIAMS NIH HHS/ -- AR 058481/AR/NIAMS NIH HHS/ -- NS 32765/NS/NINDS NIH HHS/ -- P30 DK043351/DK/NIDDK NIH HHS/ -- R01 AI064930/AI/NIAID NIH HHS/ -- R01 AI064930-04/AI/NIAID NIH HHS/ -- R01 AI068759/AI/NIAID NIH HHS/ -- R01 AI068759-05/AI/NIAID NIH HHS/ -- R01 AI076505/AI/NIAID NIH HHS/ -- R01 AI076505-02/AI/NIAID NIH HHS/ -- R01 AR044422/AR/NIAMS NIH HHS/ -- R01 AR044422-13/AR/NIAMS NIH HHS/ -- RC1 AR058481/AR/NIAMS NIH HHS/ -- RC1 AR058481-01/AR/NIAMS NIH HHS/ -- England -- Nature. 2010 Jul 8;466(7303):243-7. doi: 10.1038/nature09115.
