MIER1
Chr 1MIER1 transcriptional regulator
Also known as: ER1, MI-ER1
The protein functions as a transcriptional repressor that regulates gene expression by recruiting histone deacetylase HDAC1 for chromatin silencing. Mutations cause neurodevelopmental disorder with intellectual disability, autism spectrum disorder, and behavioral abnormalities, inherited in an autosomal dominant pattern. The gene shows significant constraint against loss-of-function variants (LOEUF 0.42), indicating that such variants are likely pathogenic when they occur.
