(1) An early IBM personal computer. See IBM PS/2.

(2) (PlayStation 2) A popular video game console from Sony. DVD based and introduced in the U.S. in 2000 after great success in Japan, the first PS2 models came with a 128-bit, 300 MHz Emotion CPU. Also included was a MIPS R3000 chip for I/O handling and backward compatibility with the earlier PlayStation. During its reign, more than 100 million PS2s were shipped worldwide.

Significant advances in processor technology were made in the following years, and Sony's PlayStation 3 (PS3) dramatically increased performance. See PS3, PS4, PlayStation and video game console.

Ringman reported that 159 were at risk for PSEN1 mutations, 19 for PSEN2 mutations, and 34 for APP mutations.
A team of scientists from Cardiff University have been examining three genes - APP, PSEN1 and PSEN2 - which are known to cause rare early onset forms of Alzheimer's.
The genetic component is most conspicuous in a relatively small percentage (< 1%) of families that carry disease-causing germline mutations in 1 of 3 genes--APP [amyloid beta (A4) precursor protein], PSEN1 (presenilin 1), or PSEN2 (presenilin 2)--that will invariably lead to AD, often at a relatively young age.
