MSGene - Gene overview of all published MS-association studies for IL1B
Back Search Methods Disclaimer Credits
 Gene: IL1B  (IL-1; IL1-BETA; IL1F2)  Entrez Gene    View on AlzGene   View on PDGene   View on SZGene
 Protein: interleukin 1, beta  (catabolin; preinterleukin 1 beta; pro-interleukin-1-beta)  ProteinLink
 Chromosome: 2   (View: 1  2  3  4  5  6  7  8  9  10  11  12  13  14  15  16  17  18  19  20  21  22  X  Y  MT)
 Status: Updated 25 November 2011 ;  ***Note that the RFLP Ava I in IL1B commonly referred to as nucleotide acid position "-511" can be assigned to two restriction sites each harboring one SNP (rs16944 and rs3087258) that both affect the restriction. Therefore this RFLP is excluded from meta-analysis.***

Source:  Source of case population -> “CL” (clinic-based), “PO” (population-based), or “CO” (community-based).
# Polys:  Number of polymorphisms tested per gene and per sample.
Onset Age and Age:  Mean or median age at onset or examination, respectively.
DX:  Criteria used to determine MS diagnosis ->  "P" (Poser criteria, 1983), "MD1" (McDonald criteria, 2001), "MD2" (revised McDonald criteria, 2005), "MD1&2" (McDonald criteria, 2001 and 2005), "O/M" (other/mixed), "U" (Unknown).
Result:  Overall conclusion reached by authors of the original publication (“positive” usually indicates significant (P<0.05) association in at least one of the performed analyses, and “negative” indicates no evidence for significant association, while “trend” indicates results in between).
(-) :  Either no data provided or in case of overlap, data included in original study.
