Findings

This rare variant was detected in a large sequencing study that screened 282 samples from different regions of the world (106 Asian,  87 African, 84 European, and five Middle Eastern), obtained from the Centre d'Etude du Polymorphisme Humain—Human Genome Diversity Cell Line Panel (CEPH-HGDP). The variant was detected in one individual of Chinese descent and appears to be benign (Guerreiro et al., 2010).

Neuropathology

Not applicable.

Biological Effect
