Our federal science funding agencies were designed to support science that is vetted and driven by scientists with a Congressional mandate to be for the public good. The OMB's proposed changes would replace that system with one driven by partisan cronies and special interests. 15/n

An especially disruptive change would be the elimination of publication costs. The move towards open access publishing--based on the idea that if the public pays for it, they should be able to read it--has resulted in skyrocketing up-front costs of $4000-$6000 or more per paper. 12/n

The new rules would also require that the budgeting for conferences is only allowable if participation is approved by the agency and included in the award when it is made. In other words, you have to specify the conferences you want to attend when you apply, and those must be pre-approved. 10/n

This work introduces a new approach for functionally annotating regulatory elements, expands the genotypic and phenotypic spectrum of MECP2 disorders, and points towards a potential contributing factor to the strong male bias in autism.

Rebecca Meyer-Schuman @rmschu.bsky.social · 12/05/2026
Notably, although one of these variants was in the MECP2 promoter, the proband had no signs of Rett syndrome, but was diagnosed with ADHD and autism. This variant decreased MeCP2 expression by ~30% in neurons, a level of reduction that we know causes autism-like behaviors in mouse models.
100
Rebecca Meyer-Schuman @rmschu.bsky.social · 12/05/2026
Sure enough, we identified two noncoding MECP2 variants that were passed down from unaffected mothers to their sons with autism. Both of these variants overlap the TF binding sites we independently identified, and both alter regulatory activity.
100
Rebecca Meyer-Schuman @rmschu.bsky.social · 12/05/2026
We hypothesized that mild variants in MECP2 might cause milder phenotypes like isolated autism, specifically in males who lacking a second X chromosome with a healthy copy of MECP2. These types of variants may contribute to the ~4:1 male bias seen in autism diagnoses.
110
Rebecca Meyer-Schuman @rmschu.bsky.social · 12/05/2026
What kind of phenotypes might these variants cause? We know that MECP2 is a dosage-sensitive gene on the X chromosome that causes syndromic neurodevelopmental disorders. Too little MECP2 causes Rett syndrome, mainly in girls, but too much MECP2 causes MECP2 Duplication Syndrome in boys.
110
Rebecca Meyer-Schuman @rmschu.bsky.social · 12/05/2026
We use a MPRA in human neurons to dissect the function of MECP2 cis-regulatory elements, mapping the active transcription factor (TF) binding sites. This helps us trace back which TFs regulate MECP2 and tells us which parts of the element are most vulnerable to pathogenic variants.
