SCREENING METHODS for TRAPSSCREENING METHODS for TRAPS Genotyping: microsatellites within (TNFRp55)
and flanking (D12S99 and D12S77)TNFRSF1A locus used to genotype family members.
DHPLC: we screened 20 ADRF families and 184 sporadic cases forTNFRSF1A mutations using the Transgenomic WAVE® System.
Sequencing: ABI 373A sequencer.
ELISA assays: used to determine serum levels of TNFRSF1A and TNFRSF1B (sTNFRSF1A and sTNFRSF1B).

A total of 8 novel TNFRSF1A mutations (T37I, D42, G46E, T50K, F60L,C70R, C70S and R92P), and 5 known (c.193-14 G>A, P46L, T50M, C88R,
and R92Q) mutations in a study of 20 families. The C70S mutation found in a Japanese patient
Affected members in 4 of the 7 families without TNFRSF1A mutations have low sTNFRSF1A
These findings indicate the presence of genetic heterogeneity in ADRFs.

Apoptosis -
A type of programmed cell death in which the cell dies (commits suicide) through a series of cellular events including enzymatic fragmentation of DNA.
# necrosis - cells bursts and discharges contents. e.g. infarction
