IQSEC2 and X-linked syndromal intellectual disability.

ABSTRACT: Despite the recent acceleration in the discovery of genetic risk factors for intellectual disability (ID), the genetic etiology of ID is unknown in approximately half of cases and remains a major frontier of genetics in medicine and psychiatry. The distinction between syndromal and nonsyndromal forms of ID is of great clinical importance, but the boundary between these clinical entities is difficult to ascertain for many genes of interest. ID is more common in men than in women, but the genetic explanation of this sex asymmetry is incompletely understood. This Review systematically examines the reported cases of X-linked ID caused by de novo loss-of-function mutations in the gene IQSEC2. This gene is largely known as a cause of X-linked nonsyndromal ID in male patients. However, depending
