Single genetic defect links many risk factors for heart disease and stroke
...s amino-acid cargo, which can then be incorporated into
the elongating protein chain. The defective base the researchers pinpointed was in the gene for the tRNA that transports the amino acid isoleucine. That defect distorted the docking region of the tRNA, preventing it from recognizing and attaching to...
Researchers discover gene mutations for Parkinson's disease

Gene for common form of Parkinson's pinpointed
...ns underlying rare forms of PD had yielded insight into
PD and aided design and testing of drug treatments. Until their studies, it was only known that PARK8 was caused by a mutation in a gene somewhere along a chromosomal region, or locus, that contained about 116 genes. The researchers had identified ...
