Coffin–Lowry syndrome is an X-linked disorder resulting from loss-of-function mutations in the RPS6KA3 gene, which encodes RSK2 (ribosomal S6 kinase 2).Multiple mutations have been identified in RPS6KA3 that can give rise to the disorder, including missense mutations, nonsense mutations, insertions and deletions.
Most Washington drivers using roundabouts don’t signal at all when exiting.
Nonetheless, due to the provision of traffic between two directions of opposing traffic, some motorists tend to maintain an ongoing criticism of the intersection. Additionally, as in the case of the half-CFI in Accokeek, the offset left-turn traffic reenters the main traffic stream via a half-signal, requiring motorists to merge from a stop ...
A large-scale screen of the Drosophila genome for mutants that exhibited axon guidance defects led to the discovery of the roundabout (robo) mutation. [9] In robo mutants, axons were observed to inappropriately cross and recross the midline. It was subsequently found that the secreted protein Slit was the ligand for the Roundabout receptor. [10]

In New Zealand, where traffic is on the left, when a road is given a green light from an all-direction stop, a red arrow can continue to display to turning traffic, holding traffic back while a pedestrian crossing on the side road is given a green signal (for left turns) or while oncoming traffic goes straight ahead and there is no permissive right turn allowed (for right turns).
One of the world's most heavily used pedestrian scrambles, the Shibuya Crossing at HachikÅ Square in Tokyo. A pedestrian scramble (or exclusive pedestrian interval) is a type of traffic signal movement that temporarily stops all vehicular traffic, thereby allowing pedestrians to cross an intersection in every direction, including diagonally, at the same time.
In Ireland, the yield sign reads yield in most areas, although in Gaeltacht (Irish-speaking) areas the text is géill slí ("yield right of way" [7]) instead. [8] [9] Signs erected between 1962 and 1997 read yield right of way, [10] which remains legally permitted. [9] Signs 1956–1962 had a blank white interior. [11]
