X-linked intellectual disability (XLID), also known as X-linked mental retardation, is a highly genetically heterogeneous condition for which mutations in 90 different genes have been identified. In this study, we used a custom-made sequencing array based on the Affymetrix 50k platform for mutation screening in 17 known XLID genes in patients from 135 families and found eight single-nucleotide changes that were absent in controls. For four mutations affecting ATRX (p.1761MT), PQBP1 (p.155RX) and SLC6A8 (p.390PL and p.477SL), we provide evidence for a functional involvement of these changes in the aetiology of intellectual disability.
