Abstract excerpt

Structural variations that affect the copy number of the MECP2 gene were shown to cause mental retardation in males by driving the overexpression of this gene. To access the impact of these rearrangements in males with unexplained mental retardation, we have performed a quantitative real-time polymerase chain reaction assay using SYBR Green I chemistry to quantify MECP2 gene copy number in 145 Brazilian males...
