Nonspecific X-linked mental retardation (MRX) patients are characterized by mental retardation, without additional distinguishing features. Consequently, MRX families can only be distinguished by mapping studies; yet, due to imprecise mapping studies performed in the past, the number of genes causing MRX is debatable, and a more precise localization for families is necessary to estimate this number. MRX 9 has been mapped to the pericentromeric region Xp21-q13. We refined the mapping of the MRX9 family to Xp11.22-Xp11.4. A sequencing analysis of three likely candidate genes in Xp11, SREB3, synapsin I, and TM4SF2, revealed no mutations.
