Genome sequencing of >2k neurons from human postmortem 🧠, spanning fetal to postnatal life, finds ~1/4 of prenatal cells carry big somatic 🧬 changes across multiple chromosomes, with most such neurons being eliminated before birth. Fascinating new paper, relevant for neurodevelopmental disorders.🧪👇
Perinatal elimination of genetically aberrant human cortical neurons - Nature
Single-neuron sequencing shows that widespread genomic abnormalities are common prenatally but largely eliminated around birth, indicating developmental genome quality control in human neurons.
