TY - JOUR T1 - GEnes and intellectual disability AU - Mitka M Y1 - 2009/06/03 N1 - 10.1001/jama.2009.757 JO - JAMA SP - 2202 EP - 2202 VL - 301 IS - 21 N2 - The researchers sequenced 720 of the about 800 known genes on the X chromosome in 208 families affected by the condition. The 9 new genes can now be added to the approximately 80 previously identified genes involved in this group of intellectual disabilities, allowing for more comprehensive genetic counseling. The researchers cautioned, however, that most of the mutated genes responsible for XLMR have not been identified.
