Function

The IQSEC2 gene encodes a guanine nucleotide exchange factor for the ARF family of GTP-binding proteins (see for example ARF1).[7]

Clinical significance

It is associated with X-Linked mental retardation 1.[7]

gollark: Neither.
gollark: GTech™ secret bases are kept secret by much more elegant and failsafe methods than just hoping nobody works out where I am sometimes.
gollark: I can fly very fast over the nether roof, so no.
gollark: It doesn't actually contain any extra information, except that CCEmuX was popular.
gollark: Great!
